A water quality sensor is a device designed to measure and monitor various parameters of water to assess its overall quality. It plays a crucial role in ensuring the safety and suitability of water for various applications, including drinking water, industrial processes, environmental monitoring, and research.Water quality sensors employ different technologies to measure key parameters such as pH level, dissolved oxygen (DO), conductivity, turbidity, temperature, and specific ions or contaminants. These sensors can provide real-time data on the chemical composition, clarity, temperature, and other important characteristics of water.
