摘要
针对环境条件要求较高的校准、测试实验室和粮库、温室等多现场多测量点的温湿度测量,介绍了以计算机技术为核心,以PIC16系列单片机、DS18B20温度传感器和HIH-3602C湿度传感器组成的温湿度测量仪系统设计方案;它能同时测量多路温湿度数据并把检测到的数据进行显示、报警、自动记录和保存下来,还可以通过RS485、局域网和管理软件系统,将管理计算机和多个测量仪系统灵活组成分布式温湿度监控、测量网络,实现了多现场多测量点的温湿度统一监视和测量;测温范围和精度:-50℃至+125℃,±0.1℃;测湿范围和精度:-40℃^+85℃,±1%。
Based on PIC16 - series single-chip microcomputers, DS18B20 intelligent temperature sensor and HIH-3602C humidity sensor, the instrument was designed and developed by using the technique of single-chip microcomputer, automatic measuring, intelligent sensors and network.. It can independently or linked with computer measure multiple temperature and humidity data on different sites. It can display real-time data and save recorded data, measuring range from -50℃ to ＋ 125℃ and precision ± 0. 1℃ for temperature; from - 40℃ to ＋85℃ and precision± 1% for humidity.
