A fan regulator regulates the power of a fan that controls its speed. Previously regulators are made with an inductor which drops the input voltage of the fan and causes the fan speed down. Nowadays regulators are making electronically. The only thing you have to do is rotate the potentiometer of the regulator & it varies the speed of the fan by controlling its input current. Now it’s a little bit of annoying to change the speed every time according to the environment. Theta’s why the idea comes of “Temperature Controlled Fan Regulator”. It controls the fan’s speed by sensing the temperature of the room or environment itself. You don’t need to change the speed every time; it will do it for you automatically according to your environment.
- Temperature sensor
- Regulator along with Microcontroller.
Working procedure of this circuit is very simple. A temperature sensor senses the temperature of the room or environment and sent it to the microcontroller. The microcontroller takes that information and process that information with some condition like if the temperature gets high then Microcontroller tells the regulator to speed up the fan and vice versa.
