Description
CHQ1838D is Infrared Receiver Module. An Infrared Receiver Module, often referred to as an IR receiver or IR sensor, is an electronic component that detects and decodes infrared signals. Infrared (IR) signals are electromagnetic waves with wavelengths longer than those of visible light, making them invisible to the human eye.
1. Detection: IR receivers are sensitive to the infrared light emitted by IR transmitters, which are commonly found in remote controls, IR blasters, and other devices. When an IR transmitter sends out a modulated IR signal, the IR receiver module detects the incoming IR radiation.
2. Signal Demodulation: IR receivers often receive modulated IR signals, meaning the intensity of the IR light is modulated (turned on and off) at a specific frequency. The IR receiver module demodulates the incoming signal to extract the original data encoded in the modulation.
