keyestudio TDS Meter V1.0 Board module Water Meter Filter Measuring Water Quality for arduino unor3

The Keyestudio TDS Meter V1.0 Board module is an easy-to-use water quality sensor compatible with Arduino controllers. Ideal for students, educators, and makers, this plug-and-play kit helps you measure Total Dissolved Solids (TDS) to determine water cleanliness.

Water cleanliness measurement

This sensor measures the total amount of soluble solids dissolved in one litre of water, reflecting its overall cleanliness. The electrode is capable of measuring conductive materials, such as suspended solids, heavy metals, and conductive ions.

Waterproof TDS probe

The included white TDS probe is waterproof and has a total length of 60cm. It features a two-needle design and connects to the module via an XH2.54-2P interface.

Technical specifications

The TDS meter operates on an input voltage of DC 3.3V to 5.5V, providing an output voltage of 0V to 2.3V with a working current of 3mA to 6mA. It supports a measurement range of 0 to 1000ppm with an accuracy of plus or minus 10% F.S. at 25 degrees Celsius.

Convenient hardware integration

For straightforward physical installation, the board comes with four 3.2mm fixed mounting holes. It connects to your microcontroller using a standard XH2.54-3P module interface.
