At the moment i only have one 3v3 8mhz arduino mini pro so only have one complete PIR. I found using these made sense as the NRF24 module runs at 3v3.

The housing on the current one is from a faulty wired pir, I removed the golf ball like lens off my pir module. I do plan on keeping the golf ball cover on future models and make my own housings.

Heres a short video of two prototype pirs controlling a couple of LED's

Here's a new video of a 4ch remote i made up for testing the main receiver.

Here's a Photo of the main controller box, I've just received my 4ch relay but not had time to fit it yet, Board on the left is a step down power supply as the camera is using 24vdc. The relay module for some reason uses a low as on and high off. I have made a temp proto shield with the outputs going through some NPN transistors i had laying around
