Microcontroller atmega8 168 328 allows dynamic and.
Temperature based fan speed controller.
Use the included temperature probe to program fan speed based on your heatsink temperature or use in manual mode to toggle between speeds.
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.
Use of embedded technology makes this closed loop feedback control system efficient and reliable.
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.
The 2n2222 transistor acts as a switch and controls the fan speed depending upon temperature.
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.
The led glows whenever the temperature exceeds 60 c.
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.
It also shows the temperature on an lcd display and the temperature range from 55 c to 125 c.
