基于nRF9E5的无线温湿度传感器网络节点设计

Design of Wireless Sensor Networks Nodes for Monitoring Temperature and Humidity Based on nRF9E5

针对实验场所和装备弹药仓库等地点需及时监测环境温湿度的需求,基于无线传感器网络设计实现了以nRF9E5芯片为核心的微型低功耗无线温湿度传感器网络节点。本文详细阐述了该节点的通信与处理模块和温湿度数据采集模块的设计,并给出了时分多址"点到多点"的节点之间无线通信的软件流程。

It is necessary to monitor temperature and humidity in places such as experimental sites and warehouse of equipment and ammunition. Based on WSN （Wireless Sensor Networks） theory, the micro sensor node using chip nRF9E5 is designed to monitor temperature and humidity. Communication and processing module and data collecting module of the nodes are designed. The software flow responsible for wireless TDMA and ＂point-to-muhipoint＂ communication among the nodes is also given in this paper.
