The PIR Sensor detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the PIR sensor outputs a high signal on its output pin.

    works well

    Overall: 5 out of 5

    Decently sensitive to about 30 feet. Sometimes will trigger at 50 or 60 with a good amount of movement (like a couple of people or a car).

    Back of board has a jumper but no clear instructions on how to set the jumper for hi or low sensitivity. Other than the jumpers which protrude from the back by somewhere between 0.25 and 0.5 inches, the back is pretty flat which makes mounting on a flat surface easier. I have previously purchased PIR sensors elsewhere where there are capacitors on the back which makes mounting difficult.

    For me, this was a very good value.
