PlantSpike是一种无线、微型、低功耗的原位低成本传感器系统。它可以无缝植入主要城市的地下位置，以测量城市土壤健康。Plant Spike集成了非接触式土壤湿度监测、温度监测、光照强度监测、先进的电源管理和蓝牙低能耗传输通信，用于将信息传输到客户端设备。凭借积极的功耗降低技术的新颖组合，该系统的使用寿命超过两年，使用500 mAh电池。通过将板载传感器连接到单芯片微控制器，每个模块的总组件和组装成本不到10美元。该传感器系统已在位于纽约市的哥伦比亚大学晨边校区的城市土壤试验台以及位于晨边高地的行道树坑内进行了测试，证明了该系统的功能性和鲁棒性。Plant Spike能够测量温度和光照范围，这些范围与纽约市气候带内土壤所经历的波动相当。
Plant Spike is an in situ low-cost sensor system that is wireless, miniature, and low powered. It can be seamlessly implanted in subsurface locations across major cities to measure urban soil health. Plant Spike incorporates noncontact soil moisture monitoring, temperature monitoring, light intensity monitoring, advanced power management, and Bluetooth low energy transmit-only communication for transmitting information to a client device. With a novel combination of aggressive power reduction techniques, the system’s lifetime is over two years with a 500-mAh battery. By connecting on-board sensors to a single-chip microcontroller, the total component and assembly cost of each module is less than $10. The sensor system has been tested within an urban soil testbed located on Columbia University’s Morningside Campus in New York City as well as street tree pits located in Morningside Heights, proving the functionality and robustness of the system. Plant Spike is able to measure temperature and light ranges that are comparable to the fluctuations experienced by soils located within the climate zone of New York City.
