with his 3D printer movements multiple

times when he wasn't wasn't around or

wasn't watching it as his printer didn't

have Wi-Fi he got no warning message

when the printer's axis got shifted or

jammed this resulted in faulty printed

parts to solve this he created a budget

friendly iot

device using a Raspberry Pi Pico and a

husky lens AI camera recognizing axis

movements the device tracks the X Y and

Z

axes the Pico communicates the detected

movements to a telegram bot providing

him with realtime updates and

notifications of potential malfunctions

related to the printer's

movements number 11 instead of relying

on manually controlled circuit breakers

cyberlab replaced them with smart

circuit breakers that provide a better

way to control his home appliances

through voice commands or a smartphone

application

Alisa

okay as the place where he lives remains

covered in snow most of the time

checking the drainage Well's water level

manually is not possible every

day the smart dashboard allows him to

track the daily water consumption and

make sure that the pump is working

properly he installed an additional

switch for the hot water boiler because

these Breakers come with a safety

feature that automatically shuts them

down if the user forgets to turn them

off after a set

period this ensures added safety and

peace of mind number 10 in this project

Giovani modified a remote control button

to open and close the front door of his

house instead of relying on a button

this time he decided to control the gate

using his

smartphone he made a controller for this

but while testing he found the signal

strength was weak so he extended the

range using a second circuit when you

press a button on the app the wi Wi-Fi

connected smart relay in the house gets

activated this smart relay then sends a

signal to the relay in the garage

prompting it to activate the garage gate

remote As a result the gate opens number

nine next on the list we have a smart

exhaust fan system powered by the esp32

microcontroller it uses an mq2 gas

sensor and the dht11 humidity

temperature sensor to keep track of gas

levels temperature and

humidity all this data is seamlessly

transmitted to the dynamic blink

dashboard providing you with real-time

insights if the system detects too much

gas levels the fan turns on to clear the

air and keep things safe and clean

moreover you can control the fan

manually using the dashboard offering

personalized control based on individual

needs or

preferences Altium is a PCB design

software that is both powerful and easy

to use with its in intuitive interface

and comprehensive set of features Altium

designer makes it easy to create

highquality PCB designs with the new

real-time component insights as you

design your PCB in Altium check the

description for more

details number eight if you're tired of

just getting reminders on your phone and

want something cooler to track your up

coming events then this led progress bar

is the perfect project for you all you

need are a Raspberry Pi Pico W and a

colorful 5volt addressable LED strip as

you tackle your tasks this smart LED bar

keeps you updated on how much of the

workday has already sailed by moreover

it changes colors to match your schedule

helping you know when it's time to

switch tasks and guess what when it's

time to finish the LED bar puts on a

beautiful rainbow light adding a splash

of Joy To Your Daily

Grind number seven next we have a chat

GPT based Voice assistance system built

on a custom PCB the project requires two

ESP 32 modules a proximity sensor serves

as a switch and allows you to give

commands upon accepting a gesture input

the voice commands are transmitted to

Google Cloud which converts them to text

and then sends them to an open I server

chant GPT processes the query and

generates a response this text response

is subsequently converted back into

voice audible through a

speaker I'm an AI digital assistant and

do not have a name number six next we

have a simple yet useful project a

circuit to monitor the temperature of

your

fridge to make this project you will

need an ESP microcontroller a

temperature sensor some some resistors

capacitors and a bit of soldering

skills the circuit runs on a 600

milliamp hour battery and takes separate

temperature readings of the fridge and

freezer

compartment this data gets updated on a

web server in real time in addition to

this the page also displays the battery

voltage and percentage this feature

notifies you to charge the battery

before it depletes

completely number five Russell has made

a special Beacon that lights up when

he's just 10 minutes away from home to

Signal the perfect time for a fresh cup

of

tea it consists of two models the first

sign consists of a small frame with LEDs

creating a sparkling effect the message

is cut out of paper and glued to fabric

using a cry cut machine while the

spherical ball consists of a simple

neopixel LED

ring the models can be controlled

together or separately using the W LED

app

but he relied on an ift web hook that

tracks his location and when he is in a

certain range it lights up the

beacon number four in order to remotely

control his telescope's cooling system

Michael relied on a home

assistant to make it work he put two

temperature sensors in the

telescope the first one is placed inside

the mirror while the other lies outside

sensing the ambient temperature

the home assistant Compares both the

temperature values and based on the

difference it then turns the cooling

system on and

off the smart dashboard makes it easy to

track the performance of the cooling

system and make certain changes from

anywhere number three though you can

unlock a door using keys why not make it

smart and control it with a

smartphone in this project Maxim used a

server mode motor that can open the door

lock either using an HTTP request mqtt

control or any other smart

dashboard the microcontroller is powered

by an AC todc converter that is attached

to the top of the

door the lock can also be opened either

using a physical push button or using

keys just in case of an

emergency number two unlike other DIY

weather stations that only check

temperature pressure and humidity

giovan's creation goes the extra

mile his weather station not only

monitors those Basics but also keeps

tabs on wind speed direction and

rainfall amount what's even cooler is

that Giovani didn't buy any fancy

gadgets he crafted his own wind speed

meter wind direction indicator and rain

gauge right in his

lab he set them up on his roof for

accurate readings the data from the

sensor can be seen on a local display

LCD or a web

server so whether you're at home or away

you can easily check the weather updates

simple

right number one now let's discuss a

complete DIY mechanim wheel robot

car this little Wonder not only rolls

around on cool Wheels but also comes

with a Nifty mechanical arm that can

effortlessly lift light to moderate

weight objects how cool is that to make

this project you'll need a 3D printer

because the entire body of the robot is

crafted from 3D printed

Parts the wheels are driven by DC motors

giving a robot its Sleek moves while the

mechanical arm is all about Precision

thanks to the servo Motors boasting a

whopping 4 degrees of

freedom but here's the best part SM you

don't need a separate controller to run

this whip out your smartphone open the

app and you're in command of this

car so these were some of the

interesting iot projects that you can

also try comment below the one you liked

the most drop a like And subscribe to
