Abstract

This article describes the design of fan speed control system based on variation of room temperature, using an Arduino microcontroller. The speed of the mono phase A. C Fan is made to vary, according to the room temperature conditions, as detected by the use of a temperature sensor. The variation in the recordings of the temperature sensor is used as an input to the Arduino microcontroller. Hence forth, the microcontroller excites the circuit responsible for driving the fan.
