How to design and produce a temperature monitoring system with good performance and achieve accurate and real-time temperature monitoring has become the main problem in designing this system. With the continuous improvement of electronic technology in our country, temperature monitoring systems consisting of microcontrollers as the core processor and temperature sensors as remote devices have gradually become the mainstream design. This paper introduces the research background and significance of temperature control system, domestic and foreign development status, low power consumption MSP430 microcontroller series, single-bus digital temperature sensor DS18B20 and other devices required for design, as well as the use of relevant software. Based on this, the system is designed, programmed, and debugged, and the circuit schematic and printed circuit board diagram of the system are drawn. This temperature monitoring system can monitor multiple points of temperature and display them in a cyclic manner. The selection display of a certain point can be realized using buttons, thus achieving real-time monitoring of multiple points of temperature.
