The Design of Intelligent Temperature Measurement System Based on The Microcontroller

As times progress and science develops, single-chip microcomputer technology has been popularized in our life, scientific research, and various fields. It has been a relatively mature technology. This paper mainly introduces a temperature measurement system based on 51 single-chip microcomputers and describes in detail the process of developing a temperature measurement system using the digital temperature sensor DS18B20. It focuses on the detailed analysis of the sensor's hardware connection, software programming, and system flow of each module. The system can measure and display the real-time temperature and set the upper and lower limits of the temperature. When the temperature reaches the upper and lower limits, the system has an automatic alarm function. The system can easily realize temperature acquisition and display. It is quite convenient to use and has the advantages of high precision, wide range, high sensitivity, small size, and low power consumption. It is suitable for temperature measurement in our daily life and industrial & agricultural production. And it can also be embedded in other systems as a temperature processing module or as an auxiliary extension of other main systems. The combination of the temperature sensor DS18B20 and 51 single-chip microcomputers realizes the simplest temperature detection system. The system has a simple structure and strong anti-interference ability. It is suitable for on-site temperature measurement in harsh environments and has wide application prospects.
