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.

Remote fan speed control circuit.

The circuit is powered by regulated 9v. 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 ac mains is stepped down by transformer x1 to deliver a secondary output of 12v 0 12v. In this tutorial you will also learn how to find the ir codes of any remote controller.

The up key increase the fan s speed while the down key decrease it. Using this circuit you can change the speed of the fan from your couch or bed. Nowadays all consumer electronics appliances or equipment has remote control facility for easy and convenient operation. Ir remote controller fan regulator using at89c2051 is a simple circuit which can control the speed of fan you can also use this circuit to control the intensity of light.

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. Three buttons are used to command the circuit. The unit provides 10 way speed control from 0 to 9. Infrared receiver module tsop1738 is used to receive the infrared signal transmitted by remote control.

Normally pedestal fan has a mechanical switch to control the speed and oscillation. In the suggested tv remote controlled fan dimmer circuit 4 triacs are proven for generating a 4 step speed control but 10 such triacs could possibly be integrated with all the 10 pinouts of the ic 4017 for gaining a fantastic 10 step discretely regulated fan speed control.
