TDS Water Quality and Conductivity Sensor

The TDS (Total Dissolved Solids) sensor is an analog module that provides information about the quality and cleanliness of water by measuring the amount of dissolved matter in the water. The higher the TDS value, the higher the concentration of matter in the water. Thanks to its wide operating voltage range from 3.3V to 5.5V and 0-2.3V analog output, it is compatible with both 5V and 3.3V logic level microcontrollers. The included waterproof probe prevents corrosion (polarization) during measurement by using an AC signal instead of DC, ensuring long-lasting and stable measurements. It is the perfect plug-and-play solution for projects such as testing the efficiency of domestic water purifiers, adjusting nutrient solution concentration in hydroponic farming systems and monitoring aquarium water quality.
