The led glows whenever the temperature exceeds 60 c.
Temperature based fan speed controller.
It also shows the temperature on an lcd display and the temperature range from 55 c to 125 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.
Use the included temperature probe to program fan speed based on your heatsink temperature or use in manual mode to toggle between speeds.
It is rated to operate over a 55 c to 150 c temperature range.
Perfect for diy or repair of led heatsink.
1n4007 diode controls the fan from being damaged.
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 has 10 0mv celsius linear scale factor.
The 2n2222 transistor acts as a switch and controls the fan speed depending upon temperature.
Includes temperature probe ideal for peltier coolers led heatsinks automatically control 4 pin cpu fan speed with this nifty chip.
