Cara buat ALARM PINTU CANGGIH pakai magnet

Summary

This video showcases a DIY project for creating an anti-theft alarm system using a magnet, relay, and motion sensor. The process involves assembling components like a 5V relay, sensor, and wiring, which are connected to trigger an audio alert when a magnet is moved, simulating an intruder detection system. The speaker explains how to wire everything together, including using audio cables to play a repeating alarm message. The final setup can be applied to protect a home, providing a simple yet effective security solution.

Takeaways

• 😀 The script describes a DIY project to create an anti-theft alarm using basic electronic components like a relay, magnetic sensor, and audio playback system.
• 😀 The project involves using a 5V relay, a Hall sensor (to detect the magnet), and a timer to activate the alarm.
• 😀 A key component of the system is a magnet that triggers the sensor when moved, activating the relay to power the system.
• 😀 The Hall sensor, which costs around 1200 IDR, is used to control the relay and magnet to detect unauthorized movement.
• 😀 The system is powered by a 5V USB cable, which supplies the necessary energy for the relay and sensor.
• 😀 The audio system is designed to play a repeating sound of the word 'maling' (thief) to alert the user when the alarm is triggered.
• 😀 A speaker is connected to the system using an auxiliary cable, and it plays the recorded audio when triggered by the magnetic sensor.
• 😀 The project emphasizes simplicity, aiming to provide a low-cost and straightforward security solution for homes.
• 😀 The alarm system is intended to be placed at a door or entry point to alert homeowners of potential burglars.
• 😀 The DIY project encourages viewers to replicate the setup with basic components and provides a step-by-step guide for assembly.

Q & A

What is the purpose of the magnet in this anti-theft system?

The magnet is used to trigger the sensor, which activates the relay and audio alarm when the door or entry is opened.

How much does the 5V relay cost according to the video?

The 5V relay costs around 6100 (currency not specified in the transcript), and it can be purchased from online shops.

What is the role of the Hall sensor in the system?

The Hall sensor is used to detect the presence of the magnet, and it helps activate the relay to power the alarm system.

What kind of power supply is required for the system?

The system uses a 5V power supply, and a USB cable is used to power the circuit.

What is the significance of the relay’s 'in', 'vcc', and 'ground' pins?

The 'in' pin is used to receive input from the sensor, 'vcc' connects to the power supply, and 'ground' provides the necessary grounding for the circuit.

How does the audio alarm function in this system?

The audio alarm plays a pre-recorded message or sound (in this case, repeating 'maling' or 'thief') when triggered by the relay, which is activated by the Hall sensor detecting the magnet.

Can this anti-theft system be used for securing a home?

Yes, the system is designed to act as a home security measure by alerting when an entry point is opened, thus scaring off potential intruders.

How are the audio cables connected to the system?

The audio cables are connected to the relay, and the speaker is linked through an AUX cable, allowing the system to play audio when triggered.

What audio file is used for the alarm, and how is it set up?

The audio alarm uses a recording of the word 'maling' (thief). It can be created and repeated through an MP3 file or audio recorder.

Is there any advice on how to install the system neatly?

While the video shows the basic assembly, viewers are encouraged to install the system neatly, especially when applying adhesive to secure the components in place, to ensure a tidy and effective setup.
