Water quality sensor is a tool utilized for measuring and keeping track of different attributes of water, including its physical, chemical, and biological properties. The sensors can identify and monitor various parameters such as pH, temperature, dissolved oxygen, turbidity, total dissolved solids, conductivity, as well as a range of contaminants or pollutants.

Water quality sensors find applications in different fields such as drinking water treatment, wastewater treatment, industrial processes, aquaculture, and environmental monitoring. By providing real-time data, they assist in evaluating the water quality, detecting potential issues, and enhancing treatment procedures.
