PIR Motion Sensor Module

My hallway light finally stops staying on all night since I paired this module with my microcontroller—the trigger detection is clean and it responds instantly to motion. Setup took me under ten minutes with the wiring pins clearly marked. Just wish it were available for retail here so I could order

Took a chance on this for a hallway light trigger, and the sensitivity range is spot-on for a 3-meter walkway. The jumper pins for retriggering made setup with my Arduino a breeze. Solid little board at this price point.

Wired this into a simple 5V setup and the detection range is plenty for a room entrance. The module triggers cleanly with no flicker, and the sensitivity knob makes tuning easy. Solid little board for the price.
