TDS Meter V1.0 Module Water Quality Sensor for Arduino

The TDS Meter V1.0 Module is a compact and easy-to-use water quality sensor compatible with Arduino controllers. Plug-and-play design makes it perfect for beginners and DIY projects.

Applications

This sensor can measure the TDS (Total Dissolved Solids) value of water, giving a clear indication of water cleanliness. The TDS (Total Dissolved Solids) value shows how many milligrams of soluble solids are dissolved in one liter of water. Generally, higher TDS values indicate more dissolved solids and less clean water. Therefore, monitoring TDS is an effective way to assess water quality.

Measuring TDS Value

The module measures the total amount of organic or inorganic substances in water, expressed in parts per million (ppm) or milligrams per liter (mg/L). It provides accurate readings, allowing you to maintain optimal water quality in aquariums, hydroponics, and other applications.
