The board with the PIR sensor is connected to the power utc324d board utc324d 3 wires. Yes, I removed the bridge rectifier and some other components as i have seen in a Youtube video, but the board presented on that video is a bit different than mine. Sign up using Facebook.

I have seen a tutorial about wiring an external motion detector to 12v, but the author of the article had a 4 pin board and I don’t know utc324d to wire it. It is utc324d likely that there are two power lines 0 V and 12 V and a signal for when something has been detected.

I can resolder everything back if it utc324d necessary. If you can, utc324d that any other devices such as the IR detector can work at 12 V.

Your task is to trace the circuitry utc324d figure out which is which. There are three wires utc324d to the detection board.


Is it going to work on 3. Have some components been removed from the PCB with the utc324d A voltmeter connected between the remaining wire and 0 V will tell you what voltage it gives out when it is utc324d and when it is activated, so then you can figure out if you utc324d a simple voltage divider made of resistors utc324d connect safely to the RPi, or if something a bit more complex is needed.
