Abstract
The design and implementation of temperature control system is based on STC89C52. Temperature data are collected by DS18B20 real-timely. Control the start and stop of the heater or cooler; setting two temperature alarm values can realize the speed of sound and light alarm; LCM1602 LCD screen display alarm value,temperature; upper and lower limit alarm value; setting three function keys adjust clock and alarm value; realization of power-off automatic data protection using AT24C02 chip; PC VC MSCOMM controls to remotely monitor the real-time temperature and store data; the overall framework of the system,the program flow chart are given; realization of the design function in the hardware platform.
