Details

TDS (Total Dissolved Solids) measures the milligrams of soluble solids dissolved in one liter of water. Generally, a higher TDS value indicates more dissolved solids and less clean water. Thus, the TDS value serves as a reference for water cleanliness.

A TDS pen is commonly used to measure TDS values, but integrating it into a control system for real-time water quality monitoring is challenging. Professional instruments offer high accuracy and control system compatibility but are quite expensive.

This TDS sensor kit provides an analog output compatible with most microcontrollers, such as Arduino. Using Arduino controllers, you can easily build a budget-friendly TDS detector to measure the TDS value of liquids.

This product accepts a wide voltage input of 3.3 ~ 5.5V and provides a 0 ~ 2.3V analog voltage output, making it compatible with 5V or 3.3V control systems or boards like Arduino, ESP32, Raspberry Pi, micro

, and LattePanda. The excitation source is an AC signal, preventing probe polarization, extending probe life, and enhancing signal stability. The TDS probe is waterproof and suitable for long-term water immersion.

This product is ideal for water quality applications, such as domestic water analysis and hydroponics.
