Adopting the AT89C51 single-chip-micro computer in the system to collected temperature from various temperature positions realizes the temperature display and alarm function. Applying AT89C51 single-chip microcomputer-based as main control chip, it realizes the muti-temperature testing by using of digital temperature sensor DS18B20, and measurement accuracy reaches to 0.5 ℃. At the time the system uses a 1602 display module to show the measured temperature values.Based on AT89C51 single-chip single-bus muti-point temperature measurement and control system抯 hardware assemble simply, reading data conveniently, high accuracy and widely temperature measuring, in the actual projects it is widely applied Keywords:digital temperature sensor;AT89C51 microcontroller; temperature measure 目 录 摘要.............................................................................................................................1 ABSTRACT.............................................................................................................2 目录.............................................................................................................................3 一 绪论...................................................................................................................4 二 系统方案设计 2.1 方案设计............................................................................................
