This project is a 2 channel infrared (IR) remote controlled relay driver with power saving. It works with 12-bit SIRC IR signals as used by Sony remote controls. The board uses Microchip's low cost PIC10F200 microcontroller along with a handful of easy to find components making this possibly the lowest cost remote controlled relay driver around. The controller also features a power save feature which reduces the relay holding voltage to 50% of the relays nominal operating voltage once the relay has switched on.
