Q & A

What is the main focus of the tutorial presented by Pascal?

The tutorial focuses on building an ESP-based motion sensor package using ESP Home, with the aim of monitoring movement to switch a light on and off using automation.

What is the difference between a passive infrared sensor (PIR) and a millimeter wave sensor in terms of occupancy detection?

A PIR sensor detects motion by measuring changes in infrared radiation caused by body heat and is cost-effective and simple for basic occupancy detection. A millimeter wave sensor, on the other hand, emits microwave pulses and analyzes the reflected signals to detect movement with more precision and can even detect the presence of a person when there is no movement.

Why would someone choose a PIR sensor over a millimeter wave sensor for a project?

One might choose a PIR sensor for its simplicity, cost-effectiveness, and quick response to significant changes in infrared radiation, making it suitable for applications like motion-activated lighting and security alarms.

What are the two states of a PIR sensor?

A PIR sensor has two states: it sends a high 5 volts signal when motion is detected and a low signal when motion is not detected.

What is the purpose of the repeat trigger and single trigger settings on a PIR sensor?

The repeat trigger setting allows the sensor to continuously detect motion and restart the delay timer with each motion, useful for tracking ongoing activity. The single trigger setting causes the sensor to trigger once and maintain the output state for a specified time, ignoring additional motion during this period.

How does the sensitivity potentiometer on a PIR sensor affect its performance?

The sensitivity potentiometer adjusts the range of detection. Turning it clockwise increases the range, while turning it anticlockwise decreases it.

What is the function of the time delay potentiometer on a PIR sensor?

The time delay potentiometer adjusts the duration for which the sensor maintains a high output signal after motion is detected. Increasing the setting with the potentiometer extends the delay, while decreasing it shortens the delay.

What are the three typical pin assignments for a PIR sensor?

The typical pin assignments for a PIR sensor are ground (GND), output/data (OUT or DATA), and VCC (power supply).

How does the tutorial demonstrate the integration of the PIR sensor with Home Assistant?

The tutorial demonstrates the integration by showing the sensor's data feed in Home Assistant, creating an automation that switches a light on when motion is detected, and using conditions to ensure the light only turns on under certain illuminance levels.

What is the purpose of the condition block in the automation created in the tutorial?

The condition block is used to ensure that the light only turns on when the illuminance level falls below a certain threshold, preventing the light from turning on in bright conditions where it might not be needed.

What is the next step in the tutorial series after adding the PIR sensor?

The next step in the tutorial series is to add a millimeter wave sensor for presence detection.

🔍 Understanding PIR Sensors vs. Millimeter Wave Sensors

This paragraph delves into the differences between passive infrared (PIR) sensors and millimeter wave sensors. PIR sensors detect general movement by measuring changes in infrared radiation caused by body heat, making them cost-effective for basic occupancy detection like motion-activated lighting and security alarms. In contrast, millimeter wave sensors use microwave pulses to analyze reflected signals, detecting even subtle movements with precision. They are suitable for advanced applications like movement detection in confined environments or areas with minimal movement. The paragraph also discusses the speed of detection and the factors influencing the choice between PIR and millimeter wave sensors, such as range, accuracy, cost, and power consumption. Pascal plans to use both types of sensors in the tutorial series, starting with the PIR sensor.

10:05

🛠️ Setting Up the PIR Sensor Hardware

Pascal demonstrates how to physically set up the PIR sensor, starting with checking the pin assignments (VCC, OUT, DATA, GROUND) and ensuring the correct order. He advises viewers to always check the pin order when working with different boards. The tutorial includes a step-by-step guide on connecting the sensor to the ESP Home system, using GPIO14 for the PIR sensor. Pascal also provides a full circuit diagram on his GitHub page for reference. The assembly process is detailed, including the use of a frame to mount the sensor and the necessary precautions to avoid damaging the components.

15:05

💻 Coding the PIR Sensor for ESP Home

The paragraph covers the coding process for integrating the PIR sensor with ESP Home. Pascal explains that the code for the PIR sensor is similar to that of a capacitive touch sensor due to their binary nature. The code involves defining the sensor as a platform GPIO, using GPIO14, and setting an ID and name. A key difference is the addition of a device class as 'motion'. The tutorial also includes instructions for installing the sensor wirelessly and checking the logs to ensure the sensor is functioning correctly. The movement detection is tested, and the results are shown in the Home Assistant dashboard.

20:08

The focus is on ensuring that the movement detection is accurately reflected in the Home Assistant interface, with the sensor's status clearly visible and functional.

25:10

🤖 Automating Light Control with Movement Detection

This paragraph introduces the concept of automating light control based on movement detection. Pascal explains how to create an automation in Home Assistant that triggers the light when movement is detected. He also discusses the importance of adding a condition to ensure the light only turns on in specific lighting conditions, using a light sensor to determine the ambient light level. The automation is tested, and a condition is added to trigger the light only when the light level falls below a certain threshold. The tutorial also covers creating a second automation to turn off the light after a set period.

30:11

🔄 Addressing Automation Timing Issues and Future Plans

Pascal addresses a potential issue with the automation timing, where the light might not turn off as expected due to repeated triggering of the sensor. He mentions that there are ways to overcome this issue and promises to cover it in a future tutorial.

hey there I'm Pascal and welcome to

another UT tomator tutorial if this is

your first time welcome to the wonderful

world of DIY Electronics with ESP home

in this series we are building an

over-the-top ESP based groom sensor

package using ESP home card to the

series above here if you've seen any of

my previous tutorial welcome back I know

that your time is valuable so the

tutorial say chapters which you can

access from the video timeline or in the

description if you want to skip to the

me staff go straight to about the P

sensor where I explain why we want to

use a passive andrate sensor in today's

tutorial we will continue to add to our

room sensor by adding a p sensor to our

ESP Home Room sensor project to monitor

movement and to switch a light on and

off using an

automation with a little twist we'll

also make the distinction between what

is movement or what is

resence if you like this tutorial please

like subscribe hit the notification Bell

this will enable the YouTube algorithm

to present this tutorial to more people

let's review our hardware and software

requirements I'll leave links to some of

the components on my ga page some of

these may be Affiliated links and I will

get back a percentage of the sales but

it will not cost you a cent more thank

you for supporting the channel for the

hardware we will need a passive infate

sensor there are various passive infate

sensors but the specific one that I will

recommend today for this tutorial is

this one it's an HC

sr501 P infrared sensor there are

alternatives there are many P sensors

however what I'm hearing is that they're

not as precise and as reactive as the

bigger one software wise we'll need home

assistant and ESP home first let me

outline what an infrared motion

detection sensor is and the reason we

would want to use

one passive aneroid sensors or P for

shorts are electronic sensors that

measure infrared light radiating from

objects in the field of view these

motion sensors are commonly used in

security alarms and automatic lighting

applications they detect general

movement but do not give information on

who or what move for that purpose an

Imaging IR sensor is required P sensors

work by using a pair of pyro electric

sensors to detect heat energy in the

surrounding environment these two

sensors sit beside each other and when

the signal differential between the two

sensor changes if a person enters the

room for for example the sensor will

engage that may mean it triggers an

alarm notify authorities or maybe just

turns on a light IR radiation focuses on

each of the two pyro electric sensors

using a series of lenses constructed in

the sign sensors housing in addition to

security and lighting applications P

sensors are also used in more advanced

applications such such as visitor

presence monitoring in robotics in

robotics for example a p sensor can be

used for movement detection enabling

robots to interact with their

environment more effectively despite the

sophisticated technology behind these

senses they are relatively easy to use

in Practical

applications let's address the elephant

in the room Motion versus presence and P

versus millimet wave passive infrared

sensors and millimet wave sensors are

both used for occupancy detections but

they function very differently and

provide very different information P

sensor primarily detects motion by

measuring changes in infrared radiation

caused by body heat they cost effective

and simple to deploy making them

suitable for basic occupancy detections

such as motion activated lighting and

Security Alarms however P sensors only

detect general movement this and do not

provide detailed information about what

moved on the other end millimeter wave

sensors emit microwave pulses that

analyze the reflected signal to detect

changes in movement and like P sensor

millimeter wave sensors can be used for

stat presence detection meaning they can

detect the presence of a person even

when there is no movement some can also

detect multiple persons and provide

information about the movement direction

of each of these people this makes the

millimet wave sensor more suitable for

advanced application such as movement

within a confined environment where are

people going but also in the cases of

tlets where we do not move move much

office or study or a TV room where

movement may not be evident and cannot

be detected by a p sensor the speed of

detection between passive infrared

sensors of p and millimeter wave sensors

can depend on various factors including

the specific sensor model and their

configuration P sensors are typically

used for movement activated system or

motion activated systems they're

generally very quick to respond when

there is a significant change in

infrared radiation such as when a person

enters a room on the other hand Millet

wave sensors emit microwave pulses and

analyzes the reflected signal to detect

changes in movement they can detect even

the most subtle movements with Precision

which may require more complex signaling

processing and could potentially produce

a slight delay however in practical

application both p and millimet wave

sensors are fast enough to meet

requirement for most use cases such as

Lightning control security system and

occupancy detection the choice between p

and millimeter wave often depends more

on factors like range accuracy cost

power consumption than speed in summary

both p and millimet wave s ens can be

used for presence detection millimeter

wave sensors provide a higher level of

detail and accuracy whereas P detects

broader movement and in my experience is

faster at detecting someone walking into

a room I want to make sure that you

understand I will be using both I found

that millimeter wave sensors are

generally slower than its counterpart

the P sensor today we are adding a p

sensor we will add the millimet wave

sensor to our room sensor package in the

next tutorial in this

series about the P sensor as you will

see later the code for the P sensor is

very simple you would even be forgiven

for thinking it's a copy of the

capacitive touch sensor P sensors only

have two states these are sent out to

the out or data pin motion is detected

bringing us a high 5 volts motion is not

detected bringing us a low however the P

sensor has various onboard settings in

addition to its spins the jumper has two

settings repeat trigger in this mode

every motion is detected and the delay

timer is restarted if motion occurs

again before the timer expires the

condone resets this allows the sensor to

repeatedly trigger as as long as there

is continuous movement it's useful for

scenarios where you want to track

ongoing motion or activity or leave a

light on while somebody is in the room

single trigger when a motion is detected

the output of the pr sensor turns High

immediately it remains high for the

duration set by the potential meter a

knob that adjusts the Sensi the

sensitivity and time delay during this

period any additional motion is not

processed and the timer does not res

essentially it trigger once and

maintains the output State for the

specified time in our project initially

we'll use the repeat trigger once we

introduce a millimeter wave we'll use

the single trigger and I'll explain why

at that time there are also two

potential meters sensitivity adjustment

potential meter clockwise will increase

the range and anticlockwise will

decrease the range of Sensi sensitivity

the time delay adjustment potential

meter clockwise increases the delay and

anticlockwise decreases the delay the

pin assignments are as follows ground

out or

data and VCC some boards are different

please check by unclipping the plastic

Dome I usually start with the following

settings single trigger over here

minimum on the time and halfway on the

sensitivity potential meter you can tune

it from here and decide how you're going

to set it

up so here is a typical infrared uh

infrared sensor or a passive infrared

sensor the first thing that I'd like to

show you is that you can clip

off the um the plastic on

top and the first thing that you that we

need to check is the three pins and the

order is VCC out of data and ground now

these are not necessarily always in the

same order I would advise you to check

every

time and then we are going to put it

back and I am going to turn it on its

side

here is the uh trigger setting I usually

put it in multiple

trigger when I am testing and

building then after that you've got the

um sensitivity potential meter which is

halfway and the timer which is at

minimum you can tun it from from here

you can chin it in whichever way you

feel comfortable with uh some need need

quite a bit of chining others work

straight out of the

box as usual because it's a binary

sensor we can use almost any free GPI

pins but we will use gp14 for the P

sensor I remind you that we are using

the following pins already gp26 for the

dht22 gp21 for the i2c

SDA gpio 22 for the

i2c and gpio 12 for the capacitive touch

sensor I will also attach a full circuit

diagram on my giab page for this

tutorial

how about we put all of this together

first I'd like to introduce you to a

little frame that I've built um for this

purpose um basically it's a um

three uh a three dupon uh

plug that goes directly

into the

P like this and then I just have the M

dupon plugs on the other side first

thing that we're going to do though is

we are going to switch

off the

um the sensor package so that we don't

blow

anything so we're going to open again to

make sure which one is our um our VCC

and the VCC is set on the purple

and that's all I need to know so we are

going to plug this into VCC the purple

oh that was a gray okay so we are going

for the purple into the

VCC if it doesn't mind there we are then

the middle one is the gray and that's

the data and the

data the

DAT is going into

[Music]

gpio4 and

gpio4 is a one right after gpio

12 so it comes or it should be coming

from over here I apologize for hiding

some of it and obviously the last one is

the blue and that is

ground assuming again that we can put it

into the G

uh come on a few moments

later okay so it is now into the ground

so to recap gray is

on

gp14 Blue is into

the negative or the ground and uh purple

is the

positive we we will now use a little bit

of tech as you can see I've put some

here which I will put over here and I am

going to mount the p over

here and stick

there and switch on the

package flashes once and it should be

online and it is

so basically we are

finished with the assembling and we can

move on to some

code I remind you that all of the code

is available on my GitHub page for this

tutorial the link is in the description

first things first we've decided that we

were going to use

gpio4 now you will be forgiven for

thinking that the code that I'm about to

paste is very similar to the capacitive

touch sensor and that's because both use

a binary gpio sensor there are some

differences and I will be pointing them

out to you so let me go ahead make a

little bit of

space um there we've made a little bit

of space I'm going to paste the code and

sort out this tabing there and there we

are we've got the passive infrared

sensor code I am going to center it in

the screen so that we can all see it

properly and as per the capactive touch

sensor it's platform gpio then we are

using gpio

14 and we are declaring an ID for it

then its name is movement the difference

here is we are defining a device class

as motion something we never did for the

capacitive touch light switch or touch

sensor next thing we need to do is to

save it and we are going to install it

wirelessly as usual and I am going to

just point out that whilst it

uploads and we'll just have to wait for

a second there you will see that the

light the blue light

flashes and that's because it's going

into a safe mode and it is uploading and

it is indicating that it is uploading

when it is finished which is

shortly there we are uh we are waiting

now for the

logs and it least yeah you saw it flash

a couple of times it should have stopped

flashing and that was it connecting back

to the Wi-Fi and here we are it has

started the logs movement sending State

off which is a default uh sign sign for

movement it hasn't picked up anything

now let's see if I can trigger

it and there you are it's picked up the

state on and it has switched light on

and that's because this is the first

time of the first time that I record

this piece okay so I will see you in the

uh web server section in a second

so we are here at the web server and uh

we going to click on visit it's going to

ask us for the username and password and

we know this because we've set it

up and apparently I can't spell admin

and my password okay and I'm going to

sign in and here we are and we are

specifically looking at movement in the

middle of

there and what I'm going to do is I'm

just going to bring my hand on within

its uh its

range yes there it is and uh it picked

up the movement that's what I wanted and

it takes

about uh 10 seconds to actually go off

and there we are okay so we are very

happy that's working we are going to go

straight into home assistant

so let's go into home assistant and the

first thing we want to check is that we

are getting the feed of the device

through to home assistant so we are

going to go to ESB home on home

assistant and uh we are going to look at

the sensor and movement currently is

clear let me pass my hand and yes it's

detected and it should go off

shortly there we are and if I pass again

it should see movement great so that's

working so now we're going to go all the

way to the dashboard if the dashboard is

a bit different to what you've seen in

the past uh I have cleaned it up and all

I did is add the light and the light

just switches the light on as you can

see and and switches the light

off uh it is a very simple card because

card sorry because it is the light card

uh let me show you where you're going to

find

that you're going to add a card and if

you go a little bit down you will find

the light card and that's the card that

I add it it's very straight forward you

point it to the uh light and that's that

okay but right now that's not what we

are interested in right now we

interested in having a feedback to see

if the movement is detected or not so I

am going to hit edit on our ESP Home

Room sensor card I going to go right at

the bottom and

move and uh ESB home movement sensor let

me try that again es oh sorry movement

move

there it is ESP home movement yes that's

the one that we're looking for I am

going to drag it all the way up because

I like movement at the top I'm also

going to go and edit it and all I'm

going to do is

move not not

movement movement I'm going to save that

and we and we're going to save the

dashboard and we now have the movement

inside of room assistant and let me show

you detected oh eco2 detected what

happened you see I break things from

time to time too uh so I'm going to go

and edit this where is oh I see what

happened okay that's fine we just going

to go EC

o 2 and there it is and we're just going

to save it I I must have missed clicked

something somewhere uh it's clear and I

put hand it's detected

and pretty much that's it we are

finished with the dashboard and uh yes

the temperature right here inside the

room is 18.8 De and as a matter of

interest um it's uh 16° outside for us

in Africa it's cold so I will see you

and let's do an

automation now that we have the uh

sensor working we can start with the

Automation and all we're going to do is

to switch our light on and off and we'll

be using the simulator we built in the

last tutorial in this series for the

demonstration that really you can use

any Smart Switch the automation yl will

be on my K on my G page link as usual in

the description

what we're going to do is when movement

is

detected we are going to take the uh ESP

room sensor Movement we and we're going

to set the simulators light from off to

on um after that we will do the inverse

of that in a separate automation now we

could do both of them in the same

automation but I don't want to overly

comp overly complicate things so let's

go to automations and uh we go to

settings automations and scenes create

new automations and oddly enough you're

going to see motion activated light

however motion activated light only does

motion activate activation of the light

we want to do one step further and I

will show you what I'm talking about in

a second so we're going to create a

brand new automation the trigger is is

going to be our

device which is as we know the room

sensor and we are going to choose ESP

room sensor movement started detecting

motion so there we are saying H we are

detecting motion to check if it works

it's pretty simple I'm going to put my

hand in front of it and it's been

triggered there are no and if we going

to go to then do and we are actually

going to put

a building block and you will see why

later right now though all I'm going to

do is take an

action and I am going to put the device

in yome device simulator turn on ESP

home device simulator simulated light no

flashing no none of that okay so what is

this if for if you've got a 2,000 wat

light outside that you want to trigger

with an infrared do you want that light

to come on in broad daylight in fact it

wouldn't even make it Dent even at 2,000

wats you don't so what we're going to do

is we are going to add a condition and

the condition is

device and we're going to go to the room

sensor and we are going to go to

elins below and um I have a little table

here um which I will put into my G up

page for this tutorial but uh the

recommended values out door is generally

about 10,000 laks indoor near window

about 1,000 laks in office we need about

500 laks in the home about 150 laks now

now I can tell you right now that the

board is receiving 258 laks so what we

are going to do is if we fall below 150

LS uh

lxs uh we are going to trigger the light

otherwise we don't now you're going to

tell me how you're going to show this

I'm going to show this to you in a

second so the new automation is going to

be called ESP home

move

M

detected okay save

now is this going to trigger the light

so let's check let's put my hand

through and movement has been detected

and the simulator light hasn't come on

what have I done wrong is it triggering

at all

is below 100 oh obviously one come

on we are above 150

laks so it can't come on so let me

switch off my uh main light that lights

me up and lights the board

up here we are and I need to wait for

about 30 seconds

for the illuminant sensor to update

there we are and we are currently at

44.2 laks so if I put my in front of the

sensor right now it should

trigger and yes it does so we are now

with a light that works and it takes

about 30 seconds to switch it off a few

moments

later it's a long 30 seconds because it

won't switch off I will have to do it

manually okay we haven't done the switch

off part yet all right so we are going

to go back and we are going to open a

new

automation when when the trigger of a

device in particular the room sensor and

when movement is STO detecting motion

right then do we do not need in this

case a building block we'll just switch

it

off okay and we're going to paste the

device it's ESP device simulator and

turn on the

ASP device simulator we want to actually

turn it

off there we

are to make it wait for a minute which I

like to do one minute or two what you

would do is you would add here 01 we're

not going to do that because we are

going to waste time if we do that and

I'm going to save it and call

it ESP

home

movement not

and we're going to save this and let's

trigger it

again and we are going to trigger it

again and it should switch off shortly

about 30

seconds there we are and it has been

triggered okay let me put the light back

on and uh

and uh one thing that we need to note is

that each time the sensor is triggered

the time it gets

reset um so if the timer if the uh if

it's retriggered again inside of Home

assistant it will just increase the time

as time goes by now as I

said about 60 seconds before you switch

off the light

uh there is also another problem that

exists I'm going to switch on the light

for you and we are going to wait about

30

seconds and it's been

triggered so I switch on the light and

my automation switches it off I will

show you how to overcome that in either

the next tutorial or possibly the next

tutorial or One A little later there are

ways is around that and I will show you

how to do that uh right now I think this

tutorial has been long enough and we are

coming to a close so here we so I'll see

you in the wrap

up now that we have movement detection

to switch light on and

off we can add presence detection using

a Mim wave sensor this is coming in the

next tutorial in the series little
