PIR sensors are used to detect motion from pets/humanoids from about 20 feet away (possibly works on zombies, not guaranteed). This one has an adjustable delay before firing (approx 0.3-18 seconds), adjustable sensitivity and we include a 1 foot (30 cm) cable with a socket so you can easily reposition the sensor or mount it using the two drills on either side

Runs on 5V-16V power (if you need to run it off of 3V you can do that by bypassing the regulator, but that means doing a bit of soldering). Digital signal output is 3.3V high/low. Sensing range is about 7 meters (120 degree cone)

Works well

Good range. Adjustable time on as well as adjustable sensitivity, so can be used with a relay to directly control anything. I used it with an Arduino and it interfaced directly to a digital pin in.I dropped one star rating as the board is fairly delicat
