本装置是由多个探测节点和一个监测终端构成的无线环境监测系统。探测节点具备对温度、湿度和光照等环境信息的采集、处理和数据收发等功能，其主控芯片采用超低功耗MSP430单片机。监测终端可向探测节点发送指令，接收节点数据并具备数据显示和打印功能。探测节点与监测终端直接通信距离达30cm，节点具备自动转发功能，增加了终端与节点的探测距离。系统设计了基于洪泛的路由机制和基于随机退避的MAC机制，各节点与终端具备了简单的自治组网能力。-This device is a DuoGe detecting node and a monitoring terminal constitute a wireless environment monitoring system. Ability to detect the node temperature, humidity and light and other environmental information collection, treatment and data transceiver, and other functions, its main control chip using low power consumption MSP430 microcontroller. Monitoring terminal can be detecting node to send command data and has received node data display and print function. Detecting node and monitoring terminal direct communication distance up to 30 cm, with automatic nodes forward function, increase the terminal and the detection range node. The system was designed based on the flooding routing mechanism and based on the random retreats MAC mechanism, various nodes and terminal with simple autonomous networking skills.
