Digital Infrared Motion Sensor (Adjustable Sensitivity)

Detects motion. For use with the Sensor Master.

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.

Detect angle: 110 Degrees

Detect distance: 7 meters
