temperature controlled dc fan using thermistor pdf

Working:

The basic working principle of temperature controlled DC fan is based on the working principle of thermistor. Thermistor is component which changes its resistance as its temperature changes. There are two types of thermistor available which are NTC i.e. negative temperature coefficient and other is PTC which is positive temperature coefficient.

In temperature controlled DC fan we have used a NTC type thermistor. It is called NTC because its resistance increases when its temperature ....etc

temperature controlled fan speed code

Introduction:
In this project we will be using the concept of firing angle to control fan speed. Basically in this project we will be controlling fan speed with respect to the temperature.
The system will get the temperature from the temperature Sensor via the ADC and it will control the speed according the set poing set by the user. The circuit consists of four switches based keypad, in which two buttons are used to increment and decrement the temperature value and the remaining two buttons are used to ac ....etc
