Remote Fan Speed Control Circuit

The ac mains is stepped down by transformer x1 to deliver a secondary output of 12v 0 12v.

Remote fan speed control circuit.

Previously we have posted very interesting project on fan regulator called light controlled digital fan regulator that uses torch light to control the speed of fan. The remote control is a cheap nec format remote usually supplied with small dvd players. Three buttons are used to command the circuit. The enter key is used to switch on or off the fan.

Buying a remote controlled fan slightly increases the cost of the fan presented here a circuit to convert your ordinary pedestal fan into a remote control pedestal fan without using any. The unit provides 10 way speed control from 0 to 9. In the proposed remote controlled fan dimmer circuit 4 triacs are shown for producing a 4 step speed control however 10 such triacs could be implemented with all the 10 pinouts of the ic 4017 for acquiring a good 10 step discretely controlled fan speed regulation. The circuit is powered by regulated 9v.

Using this circuit you can change the speed of the fan from your couch or bed. Infrared receiver module tsop1738 is used to receive the infrared signal transmitted by remote control. Nowadays all consumer electronics appliances or equipment has remote control facility for easy and convenient operation. The up key increase the fan s speed while the down key decrease it.

Arduino ir remote in this tutorial you will learn how to control the speed of a dc fan using ir remote optocoupler tip122 ir sensor and arduino uno or mega. Normally pedestal fan has a mechanical switch to control the speed and oscillation.
