With the development of integrated circuits, single chip microcomputers have been widely used in measurement and control systems, intelligent instruments, and other fields. This system takes single chip microcomputer as the core, uses temperature sensors to collect temperature data, and processes and displays it using the single chip microcomputer. This system uses four DS18B20 temperature sensors to collect temperature data, which is then sent to the AT89C52 single chip microcomputer for processing. The processed data is then displayed using a display unit. The system also employs the single chip microcomputer to set temperature upper and lower limits, and to control and monitor the temperature at different points. Furthermore, the system adopts a master-slave distributed approach to achieve remote control of the temperature. The system has the advantages of small size, light weight, low cost, low power consumption, strong control functions, and fast computing speed. Through the processing of the single chip microcomputer, the system can monitor and control multiple temperature points. The design of the system not only has practicality but also has a certain promotion value. Keywords: single chip microcomputer, temperature sensor, multi-point temperature detection
