摘要

这项工作提出了一个完全自供电，无电池远程（LoRa）为基础的漏水检测传感器系统。该系统集成了一个分层电化学能量收集器、一个dc-dc升压转换器和一个超级电容器，以满足LoRa传输的高瞬时功率需求。一旦与水接触，收集的能量就会激活无线通信，而不需要任何电池。该传感器通过硬件测量进行了验证，显示短路电流超过500 mA，激活时间低于50秒，并且在多个内墙上具有强大的性能。该解决方案标志着向可扩展、免维护和无LoRa电池的物联网（IoT）泄漏检测迈出了重要一步。

Toward Long-Range, Batteryless Water Leak Detection: A LoRa-Based Approach

This work presents a fully self-powered, batteryless long-range (LoRa)-based water leak detection sensor system. This system integrates a layered electrochemical energy harvester, a dc–dc boost converter, and a supercapacitor to meet the high instantaneous power demands of LoRa transmissions. Upon water contact, the harvested energy activates wireless communication without requiring any batteries. The sensor is validated through hardware measurements, demonstrating over 500 mA of short-circuit current, activation time under 50 s, and robust performance across multiple interior walls. This solution marks a significant step toward scalable, maintenance-free, and LoRa battery-free Internet of Things (IoT) leak detection.
