Abstract: With the rapid development of industrial technology,increasingly stringent requirements of the industrial production of various parameters (current, voltage, flow rate, temperature, humidity, pressure, etc.) control. Temperature is one of important parameters of common in the field of industrial production, industrial heating liquid temperature control is particularly important, constant temperature liquid is widely used in industrial production, according to the requirements of liquid temperature in the field of modern industrial production practice, the design of MSP430 MCU temperature measurement and control system. The design is based on MSP430 MCU as the core of the field for the industry liquid temperature measurement and control system, using DS18B20 temperature sensor for measuring temperature and setting temperature upper limit and lower limit, the use of electric heater for heating liquid target. The controllable silicon MCU control electric heater on-off allows the liquid to keep constant temperature range, and the current temperature and temperature range value is displayed on the LCD. The study of this system will have effect on the liquid temperature control in the field of development.
