3 In 1 IR Sensor based Mini Project Kit

Description

This multi-purpose IR module kit provides an easy way to create multiple sensor-based applications. Using basic electronic components, it enables hands-on learning for students and hobbyists. The included projects demonstrate the working principles of infrared sensors in real-life applications such as flame detection, remote control testing, and touchless interactions. With the possibility of expansion into other projects like object detection alarms and automated systems, this kit serves as an excellent introduction to sensor-based electronics.

Step-By-Step Instructions for Each Project

1. Flame Sensor

Objective: Detects infrared radiation emitted by fire and activates a buzzer.

Steps:

1. Connect the VCC pin of the IR module to the positive terminal of the battery.
2. Connect the GND pin to the negative terminal of the battery.
3. Connect the OUT pin of the IR module to negative terminal of the buzzer.
4. Connect the other terminal of the buzzer to the positive terminal of the battery.
5. Bring a flame (like a matchstick) near the sensor – if it detects the flame, the buzzer will sound.

2. TV Remote Tester

Objective: Detects IR signals from a remote control and activates a buzzer.

Steps:

1. Circuit is same as flame sensor
2. Press any button on the TV remote while pointing it at the sensor – if it detects IR signals, the buzzer will beep.

3. Touchless Doorbell

Objective: A doorbell that rings when a person places their hand near the sensor.

Steps:

1. Circuit is same as flame sensor
2. Place the sensor near the entrance of a door. When a hand is placed near it, the buzzer will ring.

Safety Precautions:

• Do not short-circuit the battery terminals.
• Keep the IR sensor clean for better detection.
• Do not use the flame sensor near highly flammable substances.
