Nov 13,  · Working of Temperature controlled DC fan using Thermistor. Non when the temperature is increased, the resistance of Thermistor deceases and the voltage at non-inverting terminal of op-amp becomes higher than the inverting terminal, so the op amp . The speed of the fan can be decided by the temperature examine by the microcontroller. Microcontroller controls the DC fan using the IC LD motor control. This IC LD is a dual H-bridge motor driver used to control the speed and direction of DC motor. It . Dec 14,  · Temperature Controlled DC fan using Thermistor. 3. Introduction:  Temperature controlled DC fan is a temperature based fan.  It can cool the devices by operating a DC fan when the temperature in its vicinity increases above the preset level.  Its operation is fully automatic and turns off when the temperature returns normal.

This is to certify that the work in the thesis entitled Temperature Controlled DC Fan using Microcontroller by Ghana Shyam Soren, bearing roll number EE, and Ram Ashish Gupta, bearing roll number EE, is a record of an original research work carried out by them under my. Temperature Controlled DC Fan. This circuit can cool your heat generating electronic devices by operating a DC fan when the temperature in its vicinity increases above the preset level. Its operation is fully automatic and turns off when the temperature returns normal. It uses a small 12V DC brush less fan used in computers. Mar 11,  · Working. The basic working principle of temperature controlled DC fan is based on the working principle of the thermistor. The thermistor is a 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 Author: Mayure5h.
