Motion Detection Automatic Light On/Off with Arduino | Home Automation
Scroll down for code.....
Automating home stuff is fun. In this tutorial we are using PIR motion detection sensor to detect motion and turn ON LED bulb and it will remain ON for 2 minutes if no motion detected. Obviously you can increase this time from 0.3 seconds to 5 minutes to 10 minutes. For more information you can see your manufacturer data sheet. If you are continuously in detecting zone it will not turn off, it will increase its delay time.
