System is mainly designed a microcontroller based "Tiny Cooling Fan" temperature controller, a microcontroller and sensor DS18B20 as the core, with a temperature display and fan speed control function. By understanding the microcontroller based "Tiny Cooling Fan" works and structural framework temperature controller, master the use of sensors, hardware and software full of ideas, let the system easy to use, simple. The temperature is controlled by a digital temperature sensor DS18B20 as the temperature sensing element. SCR connected in the power supply and the load "Tiny Cooling Fan", by changing the ratio of the ON and OFF in a given period of time to implement SCR speed control function, the design complete and easy to use, adapt to different occasions, people slept office It uses.
