IRDA (Infrared Data Association) is an industry-standard protocol for wireless communication using infrared (IR) light. IRDA transceivers are devices that are used to transmit and receive IR signals, allowing for wireless communication between IRDA-compatible devices. These transceivers typically consist of an IR LED and an IR detector, which are used to transmit and receive IR signals, respectively.
IRDA transceivers are commonly used in a variety of applications, including consumer electronics, industrial automation, and medical equipment. They are particularly useful in applications where short-range wireless communication is needed, such as in TV remote controls or in point-of-sale systems. IRDA transceivers are also used in some types of personal computers, where they can be used to transfer data between devices, such as between a laptop and a printer.
