Analog tds (total dissolved solids) sensor

The analog tds (total dissolved solids) sensor is a reliable water quality sensor designed to measure the concentration of dissolved substances such as salts, minerals, and metals in water. It provides a stable analog voltage output that can be easily read by microcontrollers, making it ideal for real-time water monitoring applications. With a waterproof probe and corrosion-resistant electrodes, this sensor is suitable for long-term use in various water testing environments.
