摘　　要：传感器网络作为物联网的底层核心和感知前端,在实际应用中要求能够长时间连续工作,但是基于电池的有限能源供给严重限制了其灵活设计和长期部署,成为许多领域中影响其应用的重大挑战。能量收集技术使得节点可以从环境获取能量给自身充电,为延长网络寿命提供了一个有效的技术手段。本文设计了一种基于CC2650的无线传感器网络节点,结合基于LTC3331的多源环境能量收集技术,形成了一套完整的带能量补充的微功耗传感器节点。实验通过太阳能板作为能量收集前端进行验证,结果表明其可以实现环境能量的收集和累积存储并驱动节点运行。该节点体积小,自治工作时间长,可以广泛用于环境和结构监测等领域。As the low-level key and sensing front-end of Internet of Thing （IoT） , the sensor network is required to work continuously for a long time in most applications. However, the limited pow,e r supply based on battery severely limits its flexible design and long-term deployment, which has become a major challenge in its application. Energy harvesting is a promising technique to extend the lifetime of sensor networks by recharge themselves from the available ambient harvested energy. This paper presents the design of a wireless sensor node based on multi-standard ultra-low power wireless MCU CC2650. Moreover, an energy harvesting module based on LTC3331 is added to form a complete solution of low consumption sensor node with extra energy supply. According to the experiment using a photovoltaic panel as energy harvester, the circuit can gather the environment energy and activate the wireless sensor node. It should be widely applied to various fields, such as environmental and structural monitoring, for its long lifetime and small size.
