In general, home appliance fans need to be operated manually with the help of regulators with the variation of temperature, thus requires a repeatedly extra effort for regulating the fan speed which acts to our agony. It is also a part of smart home application where the fan will gradually increase its speed if the temperature is increasing. This project is about how the speed of a fan can be controlled, based on temperature sensor. Over the last decade, advances in electronics have made devices smaller, cheaper and faster. These applications include temperature measurement, compensation, and control. Their accuracy and stability make them highly useful for a wide range of purposes. There are many potential applications for NTC thermistors. A NTC (Negative Temperature Coefficient) Thermistor is used as temperature sensor. The heart of the circuit is an Arduino board which controls all its functions.

It can monitor the temperature and displays it on an LCD display in the range of –50☌ to +150☌. In this project, I will design a practical temperature controller that controls temperature of any device according to its requirement for any industrial application.
