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.
Use of embedded technology makes this closed loop feedback control system efficient and reliable.
1n4007 diode controls the fan from being damaged.
It is rated to operate over a 55 c to 150 c temperature range.
The 2n2222 transistor acts as a switch and controls the fan speed depending upon temperature.
It has 10 0mv celsius linear scale factor.
Perfect for diy or repair of led heatsink.
Includes temperature probe ideal for peltier coolers led heatsinks automatically control 4 pin cpu fan speed with this nifty chip.
Microcontroller atmega8 168 328 allows dynamic and.
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.
