Use of embedded technology makes this closed loop feedback control system efficient and reliable.
Temperature based fan speed controller.
It is rated to operate over a 55 c to 150 c temperature range.
Temperature based fan speed controller 7 abstract this project is a standalone automatic fan speed controller that controls the speed of an electric fan according to our requirement.
In this project an 8051 based microcontroller forms the processing part which firstly senses the temperature via the adc the controller then compares the data with the set temperature which the user can set via the keypad.
Temperature based fan speed control working the proposed system is a practical temperature controller used to control the temperature of any device based on its requirement for different industrial applications.
It also shows the temperature on an lcd display and the temperature range from 55 c to 125 c.
It has 10 0mv celsius linear scale factor.
Includes temperature probe ideal for peltier coolers led heatsinks automatically control 4 pin cpu fan speed with this nifty chip.
Perfect for diy or repair of led heatsink.
1n4007 diode controls the fan from being damaged.
The led glows whenever the temperature exceeds 60 c.
