摘　　要：土壤温湿度作为农业生产的重要影响因素,对作物的生长状况起到关键性作用,实现实时、长期、连续地监测多层土壤的温湿度对于指导农事种植与操作具有重要意义。为此,针对多层土壤温湿度监测,设计了4层土壤温湿度监测节点,并提出太阳能分段利用方法设计了太阳能分段利用供电模块,使其能长期、稳定的运行。同时,利用Zig Bee网络进行数据传输,实现了低功耗、高精度、高稳定度的数据采集及传输。Soil temperature and humidity , as important factors affecting agricultural production , play a vital role in plant growth.Real-time, long-term and continuous monitoring of multilayer soil temperature and humidity can guide cultiva -tion and farming operations .This paper designs a soil temperature and humidity monitoring node for multilayer soil tem-perature and humidity research .And it includes a power module taking advantage of segmented use of solar energy .This makes the monitoring node run in a long and stable period .The monitoring node transmits data through ZigBee network . It achieves low-power , high-precision and stable data acquisition and transmission .
