Infrared remote control switcha
Source: InternetPublisher:ohahaha Keywords: Infrared remote control switch BSP receiving circuit Updated: 2020/12/11
Shown is the infrared remote control switch circuit, which is composed of a transmitting circuit and a receiving circuit
.
The transmitting circuit is mainly composed of NE555 integrated circuit and infrared transmitter VDI; the receiving circuit is mainly
composed of IC 2 and voltage comparator IC3.
Among them, IC2, LI, and C3 form a frequency selective amplifier with a resonant frequency of about 5 kHz. IC 3 is used as a comparator, and its reference
voltage is adjusted by the adjustable resistor RP3.
