Let’s get started with how to build a smart Water Quality Monitoring System using TDS sensor and ESP32 or Arduino. A TDS (Total Dissolved Solids) Sensor measures the total amount of dissolved solids in a liquid, typically water. Dissolved solids include inorganic salts and small organic substances. The measurement is expressed in parts per million […]
