Description

This paper introduces a temperature measuring system which is composed of a single chip microcomputer ADuC812, new type digital temperature sensor TMP100,LED display circuit and based on I2C bus. I2C bus which is invented by PHILIPS company needs only two signal lines (SDA, SCL), can realized perfect duplex synchronous data transmission. Using the method of hardware setting of device address, can completely avoid the disadvantages of device selection addressing, thus can make hardware system has simplifier and more flexible extension method. The key part of the system is composed of a single chip microcomputer ADuC812 which is compatible with MCS-51 and is invented by AD company in america. The software is compiled with 8051 assembly language. The data acquisitin single chip microcomputer measurement system with I2C bus fully shows the features of flexibility, precise and high integration. Proposed high accuracy measurement method to realize environment temperature measure. (authors)
