Description :

-This is a simple to use arduino motion sensor.
-It takes the sensor 1-2 seconds after turning on to get a snapshot of the still room. If anything moves after that period, the 'alarm' pin will go low.
-This sensor checks for infrared heat in its detecting angle. Human body, pets and several other things emit energy that the sensor is looking for, it compares with the snapshot and if there is a recent change it triggers.
-Ideal for Home alarm security projects and commonly found on automatic trigger light systems, where lights are ON when someone is in range and OFF when no one is around.
-The delay of sensing is adjustable via the potentiometer on the back of the sensor.
