The Gravity PIR Motion Sensor Arduino Compatible allows you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. It is small, inexpensive, low-power, easy to use and dosen't wear out.
Great little board to add motion sensing to your projects. Simple to use with a single detection/no detection signal.

Good motion sensing
I used it on a wearable project and it worked perfectly. It is small and work on 3.3v which make it perfect to work with Raspberry Pi or make it accessible for an Intel Edison.
