摘要：
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.
