摘要
针对温室环境温度监测的需求,设计了基于ZigBee片上系统CC2430和"一线总线"数字化温度传感器DS18B20的无线温度监测系统。采用了星形网络的拓扑结构,节点之间有效通信距离大于70m。CP2102支持通过USB与PC通信并供电。实现了低功耗、低成本、低布线复杂度的温室温度监测。
In order to meet the requirements of temperature monitoring in Greenhouses, a wireless temperature monitoring system is designed based on CC2430 and DS18B20 in this paper. By using star network topology, effective communication distance of the system is more than 70m. On the basis of CP2102 the system can keep communication with PC and be supplied power through USB interface. So a temperature monitoring system with low power, low cost and low wiring complexity is implemented for Greenhouses.
