摘要
根据温度分布不均匀的特点,很难用单个温度传感器获得相对准确的温度信息。使用DSl8820单总线数字温度传感器设计多传感器检测系统,利用AT89S51单片机读取DSl8820内部的温度值,通过1602液晶显示器直观的显示温度值,设计了一套多点温度检测系统。
According to the imbalance of the distribution of temperature, it is difficult to use a single temperature sensor to get accurate tem- perature information, use digital temperature sensor DS18B20 design multi sensor detection system. AT89S51 read DS18B20 internal tem- perature, through the 1602 LCD monitor intuitive display temperature, designed a multi-poiot temperature detection system
