IR Receiver Module

Very simply put, an infrared receiver module is a component that receives an infrared signal from its associated transmitter and interprets the request.

These infrared signals are transmitted to and from the IR receiver module in wavelengths of 840-960 nanometers in the near infrared range.

Many devices use an IR receiver module for wireless remote control and similar purposes, such as in television remotes or robots.

In television remote control applications, the remote sends infrared signals at a particular frequency, and the signals are received by the television. This frequency usually is set between 30 kilohertz and 60 kHz, with the most common frequencies being 36 kHz, 38 kHz and 40 kHz.

IR extenders relay the signal from one IR receiver module to another.

Additional applications that utilize an IR receiver module include three-dimensional glasses, a plethora of sensors and various human-computer interaction technologies.

HCI applications, especially as part of the Open CV library, utilize IR receiver modules in their development of technologies such as interactive whiteboards and face recognition.
