Description
IR_DoorBell
Its made with "Infra Red" leds(receiver and transmitter) from "eBay". The lighting, leafs, moving objects, shadows and wind will make a difference. Its only a first step prototype which is not recommended for real use. It needs extensive testing and a lot of improvement. During testing the "IR_transmitter" was burning a lot. Now I will replace it with a normal LED(5mm) and check the results.

Infra red DoorBell, not for critical systems !!! Prototype, simple with minimum components, might work, but it needs extensive testing.
