Water pH Monitoring with a Smart Sensor Powered by a Thermoelectric Generator with a Phase-Change Material

The quality of water supplied to the human populations should be under continuous monitorization to detect possible threats to the consumer or infrastructure. The measurement of water's pH allows to conclude about water quality. Solar thermal energy harvesting and consequent conversion into electrical energy, after properly regulated, allows to power an intelligent sensor to measure the pH values of water. The adoption of the IEEE1451 standard allows the smart sensor, through the services provided by this standard, integrate a sensor network and cooperate with other elements of the network to maximize the functionality and overall efficiency of the water distribution system.
