Remote Fan Speed Control Circuit

The up key increase the fan s speed while the down key decrease it.

Remote fan speed control circuit.

Normally pedestal fan has a mechanical switch to control the speed and oscillation. 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 enter key is used to switch on or off the fan. 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.

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. 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.

In this tutorial you will also learn how to find the ir codes of any remote controller. Three buttons are used to command the circuit. 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. The unit provides 10 way speed control from 0 to 9.

The circuit is powered by regulated 9v. 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.
