IR Transmitter

OVERVIEW:

IR Transmitter and receiver are used to control any device wirelessly, means remotely. TV remote and TV are the best example of an IR transmitter and receiver. TV generally consist of TSOP1738 as the IR receiver, which senses modulated IR pulses and convert them into an electrical signal. Here in our circuit, we are building IR remote and its receiver.  We are using IR LED as a transmitter and TSOP1738 as IR receiver.

The most common use of Infrared (IR) communication is remote controls of different appliances like TV’s. The handheld remote control of the TV consists of IR Transmitter and the IR Receiver is placed at the TV.
