Remote control facilitates the operation of fan regulators around the home or office from a distance. It provides a system that is simple to understand and also to operate, a system that would be reliable and easy to maintain and durable irrespective of its usage. It adds more comfort to everyday living by removing the inconvenience of having to move around to operate a fan regulator.

 Today, remote control is a standard on electronic products, including vicars, cable and satellite boxes, digital video disc players and home audio players. In the year 2000, more than 99 percent of all TV set and 100 percent of all VCR and DVD players sold are equipped with remote controls.

The average individual these days probably picks up a remote control at least once or twice a day.

Basically, a remote control works in the following manner, a button is pressed. This completes a specific connection which produces a code line signal specific to that button. The transistor amplifies the signal and sends it to the led which translates the signal into infrared light. The sensor on the appliance detects the infrared light and reacts appropriately.
