An infrared blaster (or IR blaster) is a device that emulates an infrared remote control to autonomously control a device that is normally controlled only by remote control key presses.
The most common use of an IR blaster is to allow a recording device such as a TV, DVD Players etc to change the channel and Volume, power, Mute etc.
This way, the recording device can automatically select the correct channel to record before starting the recording process. Another common use is to extend infrared signals in order to place remote controlled products behind closed doors.
All the Home Appliances which can work with IR Remote can control by single device called Mobile Phone (APP).
