基于MSP430F149的便携式温湿度监测仪的设计

Design of Portable Temperature and Humidity Monitor Based on MSP430F149

为了及时、方便地获取植物病害预测预报等所必需的气象数据,作者设计了一种便携式温湿度气象监测仪,并给出了其硬、软件设计方法。该监测仪以超低功耗单片机MSP430F149、智能传感器SHT15和U盘为主要元器件,能实时地进行温度、湿度和叶面湿度的采集、显示和存储。该监测仪具有体积小、重量轻、携带方便、性价比高和数据存储量大等特点,既可单独使用,也可作为下位机嵌入到系统中实现数据采集和处理的功能。

In order to obtain the necessary meteorological data for the plant disease pre diction and forecast timely and conveniently,a sort of temperature and humidity monitor was designed,and the design method of the hardware and software was introduced in this paper. By using the ultralow power consumption microcontroller MSP430F149, intelligent sensor SHT15 and U disk as the major components,the monitor can realize the real-time data acquisition,display and storage for the temperature,air humidity and leaf wetness. The monitor,with the characteristics of small volume,light weight,convenient carry,high performance-cost ratio and big data storage volume and so on,can be used either alone or embedded into the control system as a slave computer to realize the data acquisition and processing.
