In this article we will discuss IDR, will make brief discussion on IDR, last article we discuss about USB.

The Infrared Data Association (IrDA) is an industry-driven interest group that was founded in 1993 by around 50 companies. IrDA provides specifications for a complete set of protocols for wireless infrared communications, and the name “IrDA” also refers to that set of protocols.

Infrared is a form of wireless connection in which signals are sent via pulses of infra- red light. Infrared is generally used for short-range transmission of up to one meter, and can transfer data at speeds up to 16 Mbps.

Short for Infrared Data Association, a group of device manufacturers that developed a standard for transmitting data via infrared light waves. Increasingly, computers and other devices (such as printers) come with IrDA ports. This enables you to transfer data from one device to another without any cables.

Mode with maximum data size of 64 bytes. Once connection is made, the negotiated data rate can be as high as 115.2 kbps (IrDA-1.0) or 4 Mbps (IrDA-1.1), the negotiated maximum data size can be as big as 2048 bytes. Following are the advantages of Infrared sensor

➨ It provides secured communication due to line of sight or point-to-point mode of communication.

➨ The battery used in infrared devices last for long duration due to lower power consumption.

Infrared motion sensors detect motion in daytime and nighttime reliably.
