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

Automatic temperature controlled fan
Here is a scheme through which the fan can be linearly thespeed controlledautomatically, dependingon the room temperature. The scheme is effective because it ishighly control thyristors forpower. Alternatively, samecircuit can be used to automatically control AC temperaturecontrolled.In this diagram, temperature NTC thermistor is sensorused, i.e. one Havinga multiplier negative temperatures. The resistance of the thermistor in Thevalue 25 with the isabout 1 kilogram-ohm.Op Amp A1 essentially works for ASI t ....etc

Temperature Controlled Fan Using Micro controller 8051/8052 ( C Program)
I have recently made a temperature controlled DC fan whose speed increases with the rise in temperature and decrease as the temperature falls ! It has got a lot of practical usage as it does not require to manually operated and it turns off as the temperature falls below a certain threshold ! and the temperatures on which you want to change the speed or turn off the fan are completely user defined !!
The components required are:
1.AT89S51/AT89S52
2.ADC0804
3.LM35
4 ....etc
