Description Gravity: Digital Infrared Motion Sensor Arduino

This is an easy to use Arduino motion sensor. Start the sensor and wait 1-2 seconds for the sensor to take a snapshot of the space.
As soon as anything moves after that period, the 'alarm' pin will go low(Low).
This sensor monitors infrared. It sees the human body, pets and some other things.
The sensor compares the snapshot and whether a recent change has been caused.
The detection delay is adjustable with the potentiometer on the back of the sensor.
