Availability: Back Order
DFRobot Item #: SEN0018 -

This is a simple to use arduino motion sensor. Power it up and wait 1-2 seconds for the sensor 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 it's 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.Get on with your Home alarm security audit gear and experiment with this...
