Description

PIR sensors are used to detect motion from pets/humanoids from about 20 feet away (most likely works on zombies, not guaranteed). This one has an adjustable delay before firing (approx 2-4 seconds), adjustable sensitivity and we include a 1 foot (30 cm) cable with a socket so you’ll easily reposition the sensor or mount it the use of the two drills on either side

Runs on 5V-16V power (if you wish to have to run it off of 3V you’ll do this 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)

There are lots of tutorial to be had on Adafruit’s site for these sensors!
Detect motion as much as 7 meters away
Perfect for Raspberry Pi or Arduino Projects
Easy to make use of
Requires soldering of header pins
