Remote Fan Speed Control Circuit

The remote control is a cheap nec format remote usually supplied with small dvd players.

Remote fan speed control circuit.

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. The ac mains is stepped down by transformer x1 to deliver a secondary output of 12v 0 12v. Infrared receiver module tsop1738 is used to receive the infrared signal transmitted by remote control. The enter key is used to switch on or off the fan.

Three buttons are used to command the circuit. The unit provides 10 way speed control from 0 to 9. Using this circuit you can change the speed of the fan from your couch or bed. 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.

The circuit is powered by regulated 9v. The up key increase the fan s speed while the down key decrease it. Nowadays all consumer electronics appliances or equipment has remote control facility for easy and convenient operation. Normally pedestal fan has a mechanical switch to control the speed and oscillation.

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. 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.
