农田环境信息监测的无线传感器网络节点设计

摘要

针对电子信号干扰、能耗大等因素对通信能力造成的影响,设计了基于低功耗微处理器MSP430的无线传感器网络节点.通过使用MCU的不同工作模式和对无线射频模块的不同状态等节能措施,增强了节点通信能力,大幅度降低了节点的能耗.经过背景项目实际农田环境的测试证明:节点不仅能够完成对农田环境要求信息进行准备采集,网络通信效率也得到了很大提高.%Aiming at interference of electronic signal, large energy consumption and other factors impact of communications capabilities, a wireless sensor networks node based on low-power microcontroller MSP430 is designed. Through using energy-saving method of different MCU operation mode and different wireless module status, the communication capability is improved and the energy consumption of node is reduced. The actual tests show that the wireless sensor networks can get accurate information of environment and improve the efficiency of networks communication.
