Working Principles

The IR3E3146 is an infrared remote control receiver IC that operates by detecting and decoding infrared signals emitted by remote controls. It consists of a photodiode, amplifier, demodulator, and decoder circuitry. When an infrared signal is received, the photodiode converts it into an electrical signal, which is then amplified and demodulated to extract the original data. The decoded data is then available for further processing by the host device.
