摘要
介绍了一种基于1-Wire总线的多点温度、湿度测量仪的设计方案,利用集成湿度传感器HiH3610测得相对湿度,由多功能芯片DS2438测得环境温度和湿度传感器输出的电压值,单片机对DS2438传来的各采集点数据进行处理和显示。该仪器测温范围和精度为:-40℃～80℃,精度:±0.5℃;湿度测量范围:0～100%RH,精度:±2%RH。
A kind of distributed temperature and humidity measurement design based on 1-Wire bus is introduced,The HiH3610 is used to detect humidity in combination with the DS2438 multifunction chip to get the data of HiH3610 output voltage and temperature.A microcontroller is used to display and data processing.The humidity measurement range from 0% to 100%,relative humiditymeasurement accuracy up to±2%,the temperature measurement accuracy up to±0.5℃and the temperature measurement range from -40 to+80℃.
