An ir remote control repeater has been designed for taking the signals from remote control handsets and transferring them to other locations. These repeater circuits are regularly updated by the companies for improving their compatibility with wider remote control range. The best feature of the upgraded versions of the repeaters is an adjustable frequency of output which can be tuned for giving optimum range of transmission.
Imagine that your main television or the sound system has been place in the garage downstairs along with digital decoder box, satellite decoder or VCR. You have one more television in your bedroom upstairs and like to watch satellite channels in it. If you are of an inventive and innovative nature, you can decide adding a cable to the television upstairs from the decoder placed downstairs. Now with this, you will be able to watch your favourite tv channel or video in the comfort of your own bedroom but you will not be able to change the channel or turn it off from your bedroom. The replacement solution for this is installing an ir remote control repeater circuit. This circuit is able to receive the infrared signals from remote control handset and convert them into electrical signals. You have to install the receive upstairs and an infrared emitter in an appropriate location within the range of VCR or television downstairs. An uncomplicated connection of two wires joins the 2 devices together. Now, right from your own bed’s comfort, you are able to use the handset for controlling and programming the satellite decoder or VCR that is placed downstairs.
Some of the best features of an ir remote control repeater include:
• It is quite compatible with a majority of remote control handsets that operate around 30 to 40 KHz. Radio frequency or rf is the rate of oscillation or frequency within 3 Hz – 300 GHz. The range may correspond to the frequency of changing electrical signals that used for producing and detecting radio waves. rf usually means oscillations in electromagnetic radiation or electrical circuits.
• Its frequency of output carrier is adjustable for a maximum distance of transmission.
• There is no requirement for a direct electronic connection to the VCR, lcd or the television.
• Its range of operation is similar to that of a remote control handset.
• The infrared transmitter is quite small in size (around 5 mm in diameter) and can be discreetly placed anywhere in a room.
The repeaters are supplied in the form of a kit with all its components and the single-sided PCB along with a detailed operating and assembly instructions. Extra parts needed for the process of installation include power supply, suitable enclosure and an inter-connecting cable for IR emitter. An IR emitter is already included in this kit but the extra emitters are needed to be bought separately. There are some companies like jvc that also supply power supply and enclosure for their products. The kits are also available as fully tested and built units for small additional fees or charges. The basic skills of soldering are needed for completing the installation process. You can also use an ir remote control repeater for controlling toys and lighting installed somewhere at a distance.
