It can be used to measure the value of water, reflecting the cleanliness of the water. It is suitable for water quality testing in areas such as domestic water and hydroponics. Total Dissolved Solids (TDS): TDS indicates the amount of dissolved solids in 1 liter of water. Generally, the higher the value, the more impurities are present in the water, indicating lower cleanliness. This sensor can be used as a basis for evaluating water cleanliness. Compatible and Easy to Use: This sensor is plug and play, compatible with 5V and 3.3V control systems. It has a wide voltage supply range of 3.3~5.5V and provides an analog signal output of 0~2.3V. The AC excitation source effectively prevents probe polarization, prolongs probe life, and ensures stable output signals. The waterproof probe can be immersed in water for long periods of time. 100% Satisfaction: Our customers are our top priority.
