Fan Speed Control Using Remote Circuit Diagram

These circuits are based on 555 timer.

Fan speed control using remote circuit diagram.

Tested at 12v 1a dc fan. 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. You can make the circuit as per the schematic on any general purpose pcb. 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.

By this method smoothly controlled the speed of dc motor at negligible noise. Here is some circuit diagram of dc fan regulator using pwm method. 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. 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. Infrared receiver module tsop1738 is used to receive the infrared signal transmitted by remote control. The circuit is powered by regulated 9v. By using this circuit you can control the speed of dc fan by tuning the potentiometer volume control variable resistance.

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

So for example our fan capacitor is 3 wire capacitor red yellow and purple. Most stand alone adjustable thermostats i e. 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. Suggested electric fan wiring diagrams suggested primary cooling fan single speed on off using 12 volt switching devices only for primary activation note.

Hayden flex a lite or perma cool brands can provide a 12 volt output when activated. The circuit consist of minimum number of components and you can easily build.
