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

pcb layout for vehicle tracking system using gps and gsm modem

In Vehicle tracking project, you can track the location of your Vehicle. This project gives Minute-by-minute updates about vehicle location by sending sms through GSM modem. This SMS contains longitude and latitude of the location of vehicle. Microcontroller is the central processing unit CPU of our project. Microcontroller gets the coordinates from GPS modem and then it sends this information to the user in Text SMS. GSM modem is used to send this information via SMS. SMS will be ....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
