Motion Sensing Light Module

[Muris] is pumping out the home lighting hacks. He developed this motion sensing module as an add-on to the IR switch we saw last week. There’s some kind of fuse box above his entry door and its white cover, which you see above, is where he mounted an IR distance sensor to detect movement and switch on the lights. The RC5 infrared protocol is used to transmit the necessary signal to turn the lights on, then when a set amount of time has passed it will turn them back off again.

  1. I really like the looks of that IR proximity sensor (Sharp IS471F) but it looks like it has gone completely out of stock at every supplier I’ve looked at. Does anyone know something that is similar or a supplier that still has those?
