The household electric fan infrared remote controller is as shown in the figure. This remote controller has the emitter and the receiving, control parts. The infrared transmitter is designed as the astable multivibrator which is composed of the 555 and R1, W1, C1, the oscillation frequency f=1.44/(R1+2Rw1)C1, the oscillation frequency is 38kHz to drive the infrared emission diode HG310 or HG450 to output the infrared pulse. The infrared receiving tube need to use the corresponding tube, and you need to notice the optical wavelength and optical power. The IC1 uses the special infrared receiver manifold μPC1373HA.
