Temperature Data Gathering System Based on A-Wire Bus

Abstract:

DS18B20 temperature sensor is a-wire bus sensor, which can directly output digital signal and is less influenced by external interference. Its measurement accuracy is high. Freescale microcontroller is used to develop this system, which has reliable performance. It could ensure that its regular use in the actual production and living. The program is compiled in Freescale CodeWarrior integrated development environment. Experiment result states clearly that this system can monitor and display environment temperature in real-time. It has practical value.
