These PIR modules are about $4 – $5 on eBay and
can be rewired to suit my prop controller boards.
Unclip the case to reveal the PCB.
Originally there are 4 wires:
2 from the DC supply and 2 to the load.
I use 4 core security cable, but the green wire is unused.
Black goes to the – solder pad.
Red goes to either + solder pad.
Yellow goes to the – OUT solder pad
Make sure you leave the wires long enough
to fit into the slots in the plastic casing.
Snap the PIR case back together.
The 3 pin connector is wired to suit the sensor
input on my prop controllers.
