| Abstract: | DS 18B20 is a typical single-bus intelligent temperature sensor. The minimum temperature detection system composed of DS 18B20 and single-chip microcomputer AT89C52 is of simple structure, low power consumption, high temperature measurement accuracy. Application shows that the system is suitable for veg- etable sheds with multi-temperature detection. It can display and control the temperature in vegetable sheds easily and accurate, so as to guarantee the normal growth of vegetables effectively. |
