Introduction

IR Transmitter Module is designed for IR communication which is widely used for operating the

television device from a short line-of-sight distance. The remote control is usually contracted to

remote.

Since infrared (IR) remote controls use light, they require line of sight to operate the destination

device. The signal can, however, be reflected by mirrors, just like any other light source.

If operation is required where no line of sight is possible, for instance when controlling equipment in

another room or installed in a cabinet, many brands of IR extenders are available for this on the

market. Most of these have an IR receiver, picking up the IR signal and relaying it via radio waves to

the remote part, which has an IR transmitter mimicking the original IR control.

Infrared receivers also tend to have a more or less limited operating angle, which mainly depends on

the optical characteristics of the phototransistor. However, it’s easy to increase the operating angle

using a matte transparent object in front of the receiver.
