摘　　要：In this study, the green energy saving of greenhouse sensor node is de- signed to reduce the system power consumption and high efficiency. The green renewable solar energy resources are used as the energy source of nodes; the lowenergy consumed and cost effective MSP430 chip is used as the main control chip of the processor unit; the transmission frequency of the wireless transmission unit is 433 MHz, which has the characteristics of low power consumption, high signal strength, long transmission distance and small signal attenuation during the transmission; the power supply system unit is composed of monocrystalline silicon solar panel and high performance rechargeable lithium ion battery. The selection basis of each unit is clarified in detail, and optimization is performed by hardware circuit and software program to further reduce power consumption. The power consumption of the node is calculated by the experiment, and the charging conditions of the solar panel used in the node is tested. The results show that the system can achieve the setting target through the selection and design.以设施温室传感器节点的绿色节能为设计理念,以降低系统功耗和高效利用能量为目标。通过采用绿色可再生的太阳能资源作为节点的能量来源,并对系统的处理器单元、无线传输单元以及供电系统单元等进行选型并阐明选型依据,通过硬件电路和软件程序进行优化,进一步降低功耗。通过试验对节点的功耗进行了计算,并对节点的电池和电池板的使用情况进行测试。结果表明,通过选型与设计,系统能够实现设定目标。
