High precision piecewise PID control algorithm combined with PWM output control method is adopted to realize temperature control. The digital sensor DS18B20 is selected as the temperature detection element. It also includes 1602 LCD module,key adjustment input module and H bridge drive module. The actual test shows that the system has simple structure,convenient operation and excellent performance. Meanwhile,the temperature control algorithm specially designed for the system can make the semiconductor cooler better adapt to different working conditions and give full play to its refrigeration and heating characteristics.
