DIY Smart Room Light System With PIR Motion Sensor and Arduino

Hello Friends, Today’s topic is Smart Room Light system and how PIR motion sensor detects the motion and work accordingly. I am going to tell you about the project in which you will learn how you can auto turn-on the room’s light when someone comes inside the room. It starts working when someone comes in range of PIR motion sensor, it gets activated and passes signal to programmed Arduino which turns-on the light. Because it (PIR motion sensor) can detect the motion that’s why it works till someone moving in the room and after few seconds light will get turn off automatically.

To complete the project we Required:-

  1. Arduino
  2. PIR motion sensor
  3. LED
  4. Jumper wire and Breadboard

I have created the video of PIR motion sensor with Arduino so that you can understand it in a better way by watching the whole process step by step.

As you see in the video, Arduino is required a program to
run this project, I am going to share the Arduino Code and circuit diagram and you can find it at Below is the project page link.

    Can you make it so that that light stays on as long as the sensor detects someone?
