What is the IR transmitter?
Infrared (IR) transmitters are found in many everyday electronic devices such as television remote control. These devices operate in the infrared area of the electromagnetic spectrum. The IR transmitter is designed to transmit signals and commands to an electronic device through infrared waves. Infrared transmitters are a short range communication device and are not designed for long reach communication.
For many applications, IR transmitter can be used. Basically, it is used to provide commands by electronic distance from a distance without the use of cords, cables or wires. Most modern electronic devices are dominated mainly via IR transmitter, which makes the remote control devices. Very few designated buttons will become a real modern electronics such as TVs and video game systems.
TVs, stereos and many video game systems use remote controls with IR transmitters. IR transmitters can be used to edit loudSti and Channel Channel changes on TV Do not change traces and disks on a compact disk (CD) or digital versatile disk player (DVD). Some light dimmers, garage door opening and even many brands of air conditioning units can also be controlled using IR transmitters.
Most IR transmitter devices cannot transmit the signal by walls and floors, but several manufacturers sell extension systems that can be used to increase the strength and range of IR transmitter. Connected with signal extension, remote control can be used to turn off the device in one room from several rooms from here. In many cases, several components may be associated with these extender systems to increase the overall strength and range of several IR transmitters at a time.
Infrared transmitters work in the infrared part of the electromagnetic spectrum. The infrared area of this spectrum is located between the visible light and the microwave oBlast tsektrum. Near the infrared light, it offers wavelengths closer to the influences of visible light and far infrared wavelengths of light are closer to the microwave on the electromagnetic spectrum. Far infrared waves produce heat, so they can be felt. Near infrared waves, such as waves produced by IR transmitters in television remote controls, are shorter than far infrared waves and cannot be felt.
Universal remote control can be used to imitate IR signals produced mostly by other IR transmitters. In many cases, the universal remote control can replace several other IR controls. Most universal remote control manufacturers suggest their remote control using infrared transmitters that can read hundreds of IR codes.
