温度计的制作
摘要：单片机在日用电子产品中的应用越来越广泛，温度则是人们日常生活中常常需要测量和控制的一个量。本文采用AT89S51单片机、温度传感器DS18B20和液晶显示器1602A从硬件和软件两方面介绍了一款简易数字温度计的设计过程， 并对硬件原理图和程序流程图作了简洁的描述，同时本文介绍了DS18B20和1602A内部结构及工作时序，实践证明，该数字式温度计的测温范围为-55℃——+125℃，可精确到0.0625℃，具有测温精确度高，控制性能良好等特点。该温度计完全适用于一般的应用场合，也可以在高级温报警，远距离多点测温控制等方面进应用。

The thermometer
Abstract: the microcomputer in daily electronic products is widely used, the temperature is in daily life, people often need measurement and control of a quantity. Based on AT89S51 and temperature sensor DS18B20 and LCD 1602A from two aspects of hardware and software are introduced a simple digital thermometer design process, and the hardware diagram and program flow chart for a simple description, the paper introduces DS18B20 and internal structure and working 1602A sequence, and proved that the digital temperature range for the thermometer c + + - 55-125 ° c, accurate to 0.0625 degrees Celsius temperature measurement precision, good performance, high control etc. The thermometer completely suitable for general applications, also can be in high temperature alarming, distance etc temperature control points into application.
