This paper studies the temperature measurement method by using AT89C52 microcontroller and DS18B20 digital temperature sensor. Besides, the temperature sensor chip, the interface circuit of microcon- troller and temperature sensor, and the software used to collect temperature information and transfer data are studied as well. The proteus simulation result shows that this temperature measurement system is simple in struc- ture, typical in circuit and convenient to control, and the analysis is proved to be reasonable through PSPICE simulation.
