Description: DS18B20 is a kind of networking can be highly accurate digital temperature sensor with a single bus, due to its unique advantages, enabling users to easily set up from sensor networks, and enable multi-point temperature measurement circuit becomes simple and reliable. This article describes the use of DS18B20 digital temperature sensor in a single point temperature measurement under microcomputer hardware connection and software programming, and gives the software flow chart. The production design used only one DS18B20 the temperature sensor, can increase the number of DS18B20 the temperature sensors distributed multi-point temperature measurement circuit detection system, therefore, the system is highly scalable. The whole system hardware simple, reliable system and low cost.
The single-point temperature measurement system consists of sensors, microcontroller and LCD has three major components. To achieve the temperature sensor information collection, use of DALLAS s DS18B20 digital
