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

Abstract

The project is based on the working of temperature controller using LM35 and fan ascooler. The circuit automatically senses the temperature and works normally within a particulartemperature range. Above that range the sensor produces a signal and automatically turns on thecooling fan to control the testing temperature. 0-100 C electronic temperature controlled relay isa circuit using which the temperature can be controlled with the help of a LM35 temperaturesensor.The LM35 series are precision integrated-circuit temperature sensors ....etc
