Abstract

This work presents the first prototype of the Smart Pipe, a compact and intelligent wireless node hosting miniaturized sensors, embedded in a flange, for distributed and real-time monitoring of water contamination and for optimization of water treatment plants. Beyond pH and temperature, it features a low-cost and high-resolution (13 ppm, 11 ms response time) custom-designed 4-channel conductivity measurement circuit. Long-term operation and optimized on-demand maintenance are achieved by the innovative combination of an impedance sensor measuring the thickness of sludge and biofilm depositing on microelectrodes with self-cleaning capabilities offered by UV photo-regeneration of nanometric TiO2 electrodes coatings. Finally, here we also demonstrate self-powering of the unit by means of an energy harvesting control valve, regulating the flow in the water distribution network where an efficient installation of these sensors is today foreseeable.

智能管道:用于实时监测饮用水水质的微型传感器平台

这项工作展示了智能管道的第一个原型，这是一个紧凑的智能无线节点，内置微型传感器，嵌入法兰中，用于分布式和实时监测水污染并优化水处理厂。除了pH值和温度，它还具有低成本和高分辨率(13 ppm, 11 ms响应时间)定制设计的4通道电导率测量电路。通过将测量污泥和沉积在微电极上的生物膜厚度的阻抗传感器与纳米TiO2电极涂层的紫外光再生提供的自清洁能力的创新组合，实现了长期运行和优化的按需维护。最后，在这里，我们还展示了通过能量收集控制阀来调节配水网络中的流量的装置，这些传感器的有效安装是今天可以预见的。
