Design and implementation of RF controlled miniature fan

Fan is one of the unavoidable electronic equipment in everyday life. The presence of a fan in a house, office or school is not considered as a luxury on the other hand it is included in the basic requirement. Here the facility of ordinary fan is increased by making it controlled by a remote. In a remote controlled table fan, a remote is used to regulate the speed of fan and to adjust its position. Radio Frequency (RF) remote can be used for controlling speed and to swing the fan to a desired direction. Using this system, changing the speed of the fan and adjusting the direction from couch or bed or even outside the room is possible. The remote is used for controlling the speed of the fan in three different levels. This innovation finds its use mainly to help old age people who cannot walk in order to control the speed of fan. Remote controlled fan with infrared remotes are already implemented but, here radio frequency remotes are introduced so that high range is obtained as compared with infrared remote and presence of obstacles does not affect its working as in case of infrared remote.
