The led glows whenever the temperature exceeds 60 c.
Temperature based fan speed controller.
1n4007 diode controls the fan from being damaged.
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.
Use of embedded technology makes this closed loop feedback control system efficient and reliable.
It is rated to operate over a 55 c to 150 c temperature range.
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.
Perfect for diy or repair of led heatsink.
It also shows the temperature on an lcd display and the temperature range from 55 c to 125 c.
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.
Microcontroller atmega8 168 328 allows dynamic and.
Use the included temperature probe to program fan speed based on your heatsink temperature or use in manual mode to toggle between speeds.
