| Abstract: | This paper introduces the characteristics and working principle of digital sensor DS1820. By making use of the advantage of the characteristics of 1-wire digital output of DS1820 and the microcomputer technique, an automatic measuring system of temperature for grain storage based on DS1820 is proposed. And the structure and software flow diagram of the auto-measuring system are given. Based on DS1820's characteristics, the system uses less of the data bus of the microcomputer, even does not use the A/D converter, which can cut down it's capital remarkably. |
