摘要
详细介绍了一种基于51单片机和DS18B20数字温度传感器来进行温度测量的方法,包括温度传感器芯片的选取、单片机与温度传感器接口电路的设计,以及实现温度信息采集和数据传输的软件设计。DS18B20数字温度传感器是单总线器件,与51单片机组成一个测温系统,具有线路简单、体积小等特点,而且在一根通信线上,可以挂接很多这样的测温系统,十分方便。
A practical temperature measuring method based on microcontroller and DS18B20 digital temperature sensor was presented. The selection of temperature sensor chip was discussed and the design of hardware interface circuit and related software were dealt with in more details. The proposed design is simple in hardware connection lines and small in size. In addition, it is applicable for different temperature measuring systems based on DS18B20 temperature sensors hung on one communication line.
