Arduino with PIR Motion Sensor - Arduino Project Hub

Most PIR sensors have a 3-pin connection at the side or bottom. One pin will be ground, another will be signal and the last pin will be power. Power is usually up to 5V. Sometimes bigger modules don’t have direct output and instead just operate a relay which case there is ground, power and the two switch associations. Interfacing PIR with ...

PIR sensor with Relay and timing - Arduino Forum

· Hi, Again i need some help on a smal piece of code. Using a PIR sensor it outputs HIGH when there is a movement. But after "time delay" set on the sensor it outputs LOW even if there is movement. Than while its LOW it take a few seconds to notice movement again and sets output to HIGH. I'm trying (in de code) to check: when the PIR outputs LOW to delay 5 seconds and check the status …

Then we declare the relay pin as an output (signal only go from Arduino) and we declare the PIR sensor pin as input (signal only goes into Arduino). Finally, we use digitalread to get a reading from the PIR sensor which is either 0 (no motion) or 1 (motion) and store it into the variable val. Then we use an if and else statement to use this value which we stored to turn on/off the lightbulb ...
