摘要
现有的农田小气候要素主要靠人工获取,耗时费力;现有专业设备过于昂贵,不利于组建高密度的观测网。本系统是基于MSP430的小气候采集系统,精度高,超低功耗,可以在设备自身供电的条件下长时间在野外测量数据。且由于设备成本较低,可以利用多个设备组成传感器网络,并通过终端设备远程设定采样频率,从而对某一区域的土壤温湿度,空气温湿度,光照强度等信息做详细的记录。
The existing farmland mieroclimate elements mainly rely on to the artificial obtaining that is time-consuming. The professional equipment present is too expensive and not conducive to the formation of high-density observation network. This system is built based on MSP430 mieroelimate acquisition system with high-precision, ultra-low power consumption, and can be powered by the device itself under the conditions in the field for a long time data measuring. For its lower equipment costs, the composing of sensor networks can be made hy multiple devices to set the sampling frequency through the remote terminal equipment, and thus an area of soil temperature and humidity, air temperature, humidity, light intensity, and other information can be recorded in details.
