AC fan speed regulation using TV remote

Description

AC fan speed regulation using a TV remote kit is easy to turn on or off any home appliance by using a switch or by using some control mechanism as we did in many Home Automation projects. But there are a lot of applications where we need to control the AC power partially, for example, to control the speed of the Fan or the intensity of a Lamp. In this case, the PWM technique is used, so here we will learn how to use PWM to control AC fan speed.

In a remote-controlled fan regulator, we can regulate the speed of the fan by using a remote. Here the variation in the firing angle of Triac is used for regulating the speed. Any button on the remote can be used for controlling the speed of the fan. Using this kit, we can change the speed of the fan from our couch or bed. This kit is used for controlling the speed of the fan in 5 levels. This innovation can be a success only if people are made aware of its advantages and how user-friendly it is.

The remote-controlled fan regulator circuit can be used to regulate the intensity of light. This innovation finds its use mainly to help old age people who don’t want to walk in order to control the speed of the fan. It also finds its use if somebody wants to change the speed while sleeping.

• The circuit discussed in this project is only for educational purposes.
• Be advised that working with 220V AC mains voltage requires extreme precaution and safety procedures should be followed.
• Do not touch any of the components or wires when the circuit is in operation.
