CLAP OPERATED REMOTE CONTROL FOR FANS(EC)
In modern electronics,we find this clap-operated remote control system quite useful in summers as it would enable you to control the speed of your fan or cooler, besides switching it on or off. Normally, a fan has three to five speeds but this remote control can control up to ten-step speed control fan. Besides, it provides visual indication of the speed of the fan.
The sound operated switch has the advantage that the transmitter is always with you. Further it can be used in hospitals for handicapped and in houses too.
These switches may be used to control lights or fans or anything else that does not produce too loud a sound. To prevent an occasional loud sound from causing malfunction, the circuit is normally quiescent.
This circuit may be considered in four parts : sound-operated trigger pulse generator, clock pulse generator, clock pulse counter and load operator.
