Abstract A temperature measurement and control system based on CAN bus for intelligent buildings has been designed. Taking AT89S52 single-chip microcomputer as the core，CAN bus technology and digital temperature sensor DS18B20 are used to set up a node and network structure of the temperature measurement and control system for intelligent buildings，and the overall structure of the system and key software flow are given. The measuring results show that the control of the room temperature can meet the design requirements，and the system has advantages of a simple structure，energy-saving，good real-time performance and high reliability.
