Breadboard-friendly Mini PIR Motion Sensor with 3 Pin Header

Mini PIR Motion Sensor – Breadboard Friendly with 3-Pin Header – Compact motion detection for projects 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, and 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. Connect pin #1 to ground (there's a tiny minus - sign next to the pin) Connect pin #2 to output signal (there's a tiny O next to this pin that goes high and low) Connect pin #3 to power (there's a tiny plus sign next to the pin) The attached 13.8mm diameter lens is focused at 2 to 5 meters away with a 100-degree spread.  Specifications PIR sensors and the Raspberry Pi sometimes don't get along - if you're having false trigger reports, make sure the PIR Sensor is far away from the Pi.
