Automatic fan speed regulator automatically regulates the speed of the fan according to the temperature inside the room. Due to sudden changes in atmosphere because of pollution, we feel hot and after some time we feel cold. And we have to regulate the speed of fan. Hence to solve this problem we have described this simple circuit. Automatic fan speed regulator automatically regulates the speed of the fan according to the temperature inside the room.

Fan regulators have an important place in the electrical switch boards. Fan regulators are very similar to light dimmers. Their function is to regulate/control the speed of the fan and provide a convenient environment for the residents.  The traditional regulators which are bulky use a resistance having taps and connected in series with the fan. When we move the knob different amount of resistance gets inserted in the circuit. Although cheap the biggest problem with such a regulator is that a considerable amount of energy is lost in form of heat through the resistance. When the fan is operating at low speed the power loss is significant. The technologically superior electronic regulators overcome these problems by using electronic components to control the speed of the fan.
