摘要
本文采用NTC热敏电阻温度采集,STC15F2K60S2单片机为主控芯片,以PID为核心算法、PWM控制方式控制半导体制冷片,实现恒温的温度控制系统。硬件主要分为电源压降电路、温度采集电路、温控电路等三大部分。
In this paper,NTC thermistor temperature acquisition,STC15 F2 K60 S2 single-chip microcomputer as the main control chip,PID as the core algorithm,PWM control mode control semiconductor refrigeration sheet,to achieve a constant temperature control system.Hardware is mainly divided into power supply voltage drop circuit,temperature acquisition circuit,temperature control circuit and so on three major parts.
