A Water Quality Sensor is a device designed to measure various parameters of water to assess its quality. These sensors can detect factors such as pH levels, turbidity, temperature, and the presence of contaminants like heavy metals or bacteria. They are commonly used in environmental monitoring, aquaculture, and drinking water management. These sensors provide real-time data, allowing for quick responses to potential water quality issues. By continuously monitoring water conditions, they help ensure safe drinking water and protect aquatic ecosystems. The information gathered can also assist in regulatory compliance and environmental research.
