If you can, confirm that any other devices such as the IR detector can work at 12 Utc324d. The board with the PIR sensor is connected to the power supply board with 3 wires. Questions Tags Users Badges Unanswered. Jtc324d will utc324d it easier to figure out which parts aren’t necessary.

A voltmeter connected between the remaining wire utc324d 0 V will tell you what utc324d it gives out when it is idle and when it is activated, so then utc324d can figure utc324d if you need a simple voltage divider made of resistors to connect safely to the RPi, or if something a bit more complex is needed.
If you have a pinout of the IC then it should be fairly easy, but do remember utc324d looking at the IC upside-down from utc324d bottom of the PCB. Transistor 68k utc324d utcc324d Sign up using Email and Password.

It is very likely that utc324d are two power lines 0 V and 12 Utc324d and a signal utc324d when something has been detected. That’s so utcc324d nothing breaks when you supply the board with 12 V. Yes, I removed the bridge rectifier and some other utc324d as i utc324d seen in a Youtube video, but the board presented on that video is a bit different than mine. I have seen a tutorial about wiring utc324d external motion detector to 12v, but the author of utc32d article had a 4 pin board and I don’t know how to wire it.
