Arduino PIR Motion Sensor Tutorial
PIR modules have a 3-pin connection at the side or bottom. The pinout may vary between modules so triple-check the pinout! It’s often silkscreened on right next to the connection (at least, ours is!) One pin will be ground, another will be signal and the final one will be power. Power is usually 3-5VDC input. When object comes in detecting area it will return 1 from output pin otherwise it return 0. The IR sensor itself is housed in a hermetically sealed metal can to improve…
