Arduino and PIR motion sensor based automatic multiple light control system. Room light on - TableLamp off. Room light off - TableLamp on. Perfect device for study. Control things by just waving at them. I've  built a PIR motion sensor based automated light / Appliances project which can be found  here . This project is a bigger version with relay to control 220V lights. FEATURES-  Table lamp ON main Light OFF  Table lamp OFF main Light ON PARTS YOU'LL NEED - Arduino pro mini (or any board) 2 Channel relay module Buzzer PIR motion sensor 220v to 5v converter wires hot glue THE CIRCUIT DIAGRAM: Making the project: I've  built a PIR motion sensor based automated light / Appliances project which can be found  here . This project is a bigger version with relay to control 220V lights. Just added the lights switch wires to relays and powered the arduino and relay module using a 220 to 5v converter...

Move your Hand around - Lights ON, move hands over again - Lights OFF, sounds cool  right? Today we'll be making an automatic system to control appliances by hand gesture or Motion sensing using just Arduino and PIR sensor. In our project we'll make an Emergency light that lights On / Off by just moving your hand around it. In another word gesture or wave controlled light system. This can be used as an emergency light - when you reach home it'll automatically switch the lights on. So  our goal is to make a system that switches on once you wave at it, and switches off when you wave it back again. There's Some issues to keep in mind before you'd work with PIR sensor. PIR doesn't work properly  for  at  least  one  minute when starts . PIR output value is always 1  for  some  seconds. It some times doesn't read motions. T o Solve that I've made a simple algorithm that's explained  Here . Circuit Diagram ...
