So based on single chip microcomputer as the core temperature gathering and control system to meet the people of the requirements, this thesis with STC89C52RC MCU as the master device, with digital temperature sensor DS18B20 the temperature value of the collection, and the current temperature value displayed by LCD12864; When the temperature higher or lower than expected, to control the motor by L298N to real-time control of temperature, the temperature reached expectations. The hardware design of this system include the single chip microcomputer minimum system, temperature detection circuit, LCD display circuit, key control circuit and the motor control circuit. Software design includes the main program, temperature detection subroutine, button detection subroutine, LCD liquid crystal display subroutine, motor control subroutine. Key Words ： microcontroller ； DS18B20 ；...
