Cooling Fan Controller Using Temperature Sensor LM35

The project presented here is a low-cost solution for heat management of the heatsink and various equipment that requires automatic control of a cooling Fan. The project is built using a very cheap LM358 OPAMP. LM358 is used as a comparator, and a trimmer PR1 is provided to set the...

PWM Temperature Controlled FAN using TC648 and NTC sensor

The project described here is a switch mode fan speed controller for use with brushed or brushless DC motors. Temperature proportional speed control is accomplished using pulse width modulation (PWM). 10K Ohms NTC is used to sense the temperature. The project is built using TC648 chip...
