This is a nice IR based motion detector module. Fairly low power consumption and very easy to use. Just connect the VCC and ground and you'll get a ~4V high logic signal from the middle pin when the sensor is triggered. Tthere are two trimmers on the board but I don't know what they are for (maybe sensitivity and delay?). I had to turn them counterclockwise almost all the way to get the sensor working as I expected.
