IR is an infrared photoelectric sensor unit that integrates an infrared transmitter and receiver. It connects to the M5Core via the HY2.0-4P interface and controls the infrared transmission and reception. It supports infrared encoding and decoding. Due to its reliable short-distance transmission characteristics, infrared remote control is widely used in household appliances and consumer electronics in daily life. Features 1 x Infrared transmitter (wavelength: 940nm) 1 x Infrared receiver… (M5Stack U002)
