PIR sensors are used to detect motion from pets/humanoids from about 5 meters away (possibly works on zombies, not guaranteed). This sensor is much smaller than most PIR modules, which makes it great for unobtrusive projects. It's also fully-contained - only needs power and ground, and it's breadboard or perfboard friendly.
Usage is super simple: You can power it from 3 to 12V DC, there's an onboard regulator. Digital signal output is 3.3V high/low. The signal goes high when motion is detected, and stays high for another 2 seconds, so you have plenty of time to read the value.

- Working temperature: -20 - +60 °C
- PCB dimensions: 10mm*8mm
- Module lens: small lens
- Based on AM312
