摘要
该文介绍了分布式无线露点压力监测系统的设计开发过程。主控制器采用STM32F103ZET6超低功耗32位处理器,传感器采用高精度温湿度传感器SHT75,可以同时实现温度、相对湿度和露点温度的测量,并且可以对其输出的数字量进行线性化和温度补偿,获得较高的测量精度。在完成露点温度测量的同时,还采用了MS5541C压力传感器测量气体压力,解决了目前露点测量仪功能单一的问题,扩充了仪器功能和适用范围。
This paper introduces the design and development process of distributed wireless dew point instrument.Main controller uses STM32F103ZET6 ultra low power 32 bit processor,sensor with high precision temperature and humidity sensor SHT75,can also realize the temperature,relative humidity and dew point temperature measurement,and can be linear and temperature compensation to the digital quantity output, measured with high precision.At the completion of dew point temperature measurement,at the same time, the MS5541C pressure detection module of gas pressure measurement is adopted,it solves the problem of single function of dew point meter,expand the instrument function and scope of application,
