摘要
为解决农业、气象研究领域对温度、湿度、露点同时高精度测量与仓储、医疗、食品等行业对高精度温湿度的需求,以及传统湿度测量精度低、稳定性差和校准难度大等缺点,设计了便携式温湿度露点测量仪。采用基于CMOSensTM技术的单片全校准温湿度传感器SHT75,以超低功耗单片机MSP430F1132为核心进行数据处理,实现了对温度、湿度、露点进行高速、高精度的测量。仪器具有自校准、自恢复、测量工作时间长、稳定性高等优点,目前已经成功应用于农业温室和仓储中。
For settling measurement temperature, humidity ＆ dew point in agriculture, weather, storage, medical treatment field, and the shortcoming of low precision, bad stability and hard calibrate difficulty, so designed a portable measurement for measuring temperature, humidity＆ dew point. This measurement using the SHT75,and the MSP430F1132 which using as a core for data processing. It can measure measurement temperature ,humidity＆ dew point higher speed ,precision and longer working time. Now ,this instrument is successed using in agriculture greenhouse and storage.
