This paper introduces the theory and methods of realizing an automatic temperature control system in a foot massage machine based on MCU implementations.This system achieves the functions of real-time temperature display and target temperature adjustment by buttons and solves the problem of over heating or cooling of the wire during the heating or cooling process with the perfect performance of traditional 51 series MCU,highly efficient and stable power supply,external pin interrupt,timers,PID algorithm and DS18B20 temperature sensor.It has the advantages of low cost,high precision of temperature control,adjustable target temperature and stable and reliable operating process.

Key words: MCU;PID;switching power supply
