Automate Light with PIR sensor

In this Project I tell you how we can use PIR sensor or motion sensor with light. No need to switch on lights by hands, just install this system, yours lights will be automated. I use Arduino for time setting and bd139 transistor and relay for switching.This video about PIR Motion Sensor and Arduino for making automatic light. With this video, you will learn how to connect PIR sensor with Arduino and program the Arduino to detect any moment in the room or around the motion sensor.

To make this Project I am using:-

Arduino UNO

PIR Motion Sensor

Jumper wire

Breadboard

12 volt relay

Bd139 transistor

2.2k Resistor
