Tiny Cooling Fan temperature controller

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 "dota雷竞技 " 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 "dota雷竞技 ", 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.
