SCM uses a current popular AVR chip ATMEGA8, infrared remote control signal emitted by TSOP1738 demodulation, the transmitted to the MCU I/O port, single chip to decode a certain timing and get key code, key code according to different control relays K1 and K2, to achieve the appropriate output port connected to the relay' s opening and the electrical power off function. D1 and D2 K1 and K2 used to synchronize the switching instructions state, Q1 and Q2 are used to drive relay K1 and K2. R4, and C3 form TSOP1738 supply pins on the filter circuit, played a role in anti-interference. Electricity
