根据农业大棚温湿度控制的实际需要，设计了基于 MSP430 F427的低功耗温湿度测量仪。MSP430 F427连接温湿度传感器SHT10，对农业大棚内的温湿度进行采集，将测量的结果在液晶屏上实时显示，并将数据进行存储。测量仪采用锂电池供电，结合 MSP430 F427的低功耗睡眠模式与传感器 SHT10的定时断电，单节锂电池充满电后能使测量仪连续稳定地工作6个月以上，并且系统可扩展太阳能充电功能。同时，给出了设计的结构框图，详细描述了温湿度采集电路、USB 接口通讯电路、段式液晶显示电路和锂电池供电电路等硬件电路设计，最后给出了系统软件程序流程图。试验证明，该温湿度测量仪能够准确地采集到农业大棚内的温湿度数据，为合理安排农业生产提供了充分的依据。

The low-power temperature and humidity measuring instrument is designed , according to the actual need of agricultural greenhouse temperature and humidity control . MSP430 F427 connects temperature and humidity sensor SHT10 , collects the temperature and humidity inside the agricultural greenhouse , then displays the real-time measure-ment result on the LCD screen and stores the measurement result .The measuring instrument is Lithium battery-powered , it can work continuously and stably for six months or more by using a single fully charged Lithium battery , combined with the low-power sleep mode of MSP 430 F427 and timing off of sensor SHT 10 , while the solar charging function can be ex-tended to the system .The article shows the block diagram of the design and gives a detailed description of the tempera -ture and humidity acquisition circuit , USB interface communication circuit , segment LCD circuit , Lithium battery power supply circuit and the other hardware circuit design , and then gives system software program flow chart .Tests show that temperature and humidity measuring instrument can collect the temperature and humidity data inside the greenhouse accu -rately , provide an adequate basis for arranging agricultural production reasonably .
