1)Objective:
This project will show you how to use Arduin to drive HC-SR501 infrared motion sensor and detect human motion.
2)Parts and Devices
1 x Arduino UNO
1 x HC-SR501 infrared motion sensor
1 x USB cable
1 x 2-channel relay
1 x RED LED
1 x BLue LED
1 x Breadboard
Jumper wires
3)Circuit graph
4)sample code link
down load motion sensor relay sample code
5)Result
When human is moving close to motion sensor, relay channel one will open and channel 2 will close, RED LED will turn on and blue LED will turn off. When human is moving away from sensor, relay channel 1 will close and channel 2 will open. Red LED will turn off and Blue LED will turn on. Picture as following:
