PIR sensing units are used to find motion from pets/humanoids from about 20 feet away (possibly deals with zombies, not guaranteed). This one has an adjustable hold-up prior to firing (approx 2-4 seconds), adjustable level of sensitivity and we include a 1 foot (30 cm) cable television with a socket so you can easily reposition the sensing unit or mount it utilizing the 2 drills on either side
Operates on 5V-16V power (if you require to run it off of 3V you can do that by bypassing the regulator, however that suggests doing a bit of soldering). Digital signal output is 3.3 V high/low. Sensing variety is about 7 meters (120 degree cone).
There are many guide available on Adafruit’s website for these sensors!
- Identify motion as much as 7 meters away
- Perfect for Raspberry Pi or Arduino Projects
- Easy to utilize
- Needs soldering of header pins
