Fan Speed Control Using Remote Circuit Diagram

The circuit is powered by regulated 9v.

Fan speed control using remote circuit diagram.

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. Using this circuit you can change the speed of the fan from your couch or bed. Construction of remote controlled fan regulator. Here is some circuit diagram of dc fan regulator using pwm method.

Fan regulator using triac circuit diagram the simple homemade fan regulator working based on a triac and diac bt136 is used in this circuit to control the ceiling fan speed. Infrared receiver module tsop1738 is used to receive the infrared signal transmitted by remote control. The ac mains is stepped down by transformer x1 to deliver a secondary output of 12v 0 12v. So for example our fan capacitor is 3 wire capacitor red yellow and purple.

You can make the circuit as per the schematic on any general purpose pcb. By using this circuit you can control the speed of dc fan by tuning the potentiometer volume control variable resistance. Most stand alone adjustable thermostats i e. The circuit consist of minimum number of components and you can easily build.

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. To ease your job we are giving the pcb layouts too so that you can make the pcb at your home using the etching method you may also have the pcbs made from any fabrication house too. Tsop1738 is used in the circuit for sensing the infrared signal output from remote. So in the the above diagram i shown the switch in 4 types of diagrams.

Here is the fan speed low high and med speed direction diagram so as you know that by using 3 wire capacitor we can control the speed of motor using speed regulator switch. Suggested electric fan wiring diagrams suggested primary cooling fan single speed on off using 12 volt switching devices only for primary activation note. 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. Ir infrared remote controlled switch circuit diagram for light fan appliance this homemade wireless remote controlled switch system is very easy to construct and can change our living experience.

Tested at 12v 1a dc 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.
