IrDA Transceiver Modules
IrDA, the Infrared Data Association, is an organization that aims to standardize infrared communication protocols. IrDA Transceiver Modules (IrDA Transceiver Modules) is a hardware component based on this standard, which can send and receive infrared signals to achieve wireless data transmission in a short distance. Such modules typically contain an infrared transmitter and a receiver, as well as associated control circuits, allowing devices to communicate without physical contact. The working principle of IrDA Transceiver Modules is based on infrared modulation and demodulation. The transmitter converts the electrical signal into infrared light signal, which is sent out by infrared LED; The receiver captures the infrared signal through an infrared photodiode and converts it back to an electrical signal. Since infrared rays cannot penetrate solid obstacles, IrDA communication usually requires a direct line-of-sight connection between devices, which limits their communication distance, generally within a few meters, but also reduces interference from other signals, providing a relatively safe point-to-point communication method.
