PIR Motion Sensor stands for Passive Infrared Motion Sensor, which is used to sense the motion. PIR Motion Sensor is capable of increasing or decreasing the sensitivity through a potentiometer.

In this project, we are going to test the sensitivity and turn light and buzzer ON and OFF.

3 Steps then see the Magic

Step 1: Setup

We do not need to set up a bunch of tools just install Arduino IDE for Code, Debug, and Burn the Code into IC

Step 2: Code

Step 3: Wiring

To develop this project we are going to use these components :

• Arduino Uno
• PIR Motion Sensor
• Buzzer
• LEDs
• Breadboard
• Jumper Wire

Conclusion

This project is based on Motion Sense that means if someone moves around sensor then it gives some value so here we just turn on LED and Buzzer ON and OFF. You Could make better than this project, keep in touch with us.
