Description :

-The Gravity: Analog TDS Sensor/Meter for Arduino is a kit for measuring the TDS (Total Dissolved Solids) value of water to reflect its cleanliness.
-TDS values indicate the amount of soluble solids dissolved in one liter of water, and a higher TDS value generally means less clean water.
-TDS pens are commonly used to measure TDS values, but they cannot transmit data for online monitoring or analysis.
-Professional instruments for measuring TDS values have high accuracy but can be expensive for ordinary people.
-The Gravity: Analog TDS Sensor/Meter for Arduino kit is compatible with Arduino controllers and is easy to use, with a plug-and-play design.
-The sensor supports a wide voltage input range of 3.3-5.5V and has an analog voltage output range of 0-2.3V, making it compatible with 5V or 3.3V control systems or boards.
-The sensor uses an AC signal as an excitation source to prevent probe polarization and prolong its lifespan, as well as increase the stability of the output signal.
-The TDS probe is waterproof and can be immersed in water for long-term measurements

•Wide Voltage Input: 3.3~5.5V
