PIR Motion Sensor - With Relays - Project Guidance ...

· Hello, I am working on a project where a PIR motion sensor triggers an 8 channel relay. The relays turn on at different times. I could not find a code online for this so I took it upon myself to attempt to write it myself. However, when I set it up, the relays go off by themselves even with no motion. it seems that they are in a loop.

PIR Sensor Circuit and Working with Applications

PIR sensor consists of three pins, ground, signal, and power at the side or bottom. Generally, the PIR sensor power is up to 5V, but, the large size PIR modules operate a relay instead of direct output. It is very simple and easy to interface the sensor with a microcontroller. The output of the PIR is (usually digital output) either low or high.
