About this item

The Gravity Analog TDS Sensor Meter for Arduino measures Total Dissolved Solids (TDS) in water, indicating water quality. It operates at 3.3V to 5.5V, providing a 0–2.3V analog output compatible with most microcontrollers. The sensor uses an AC excitation signal to prevent probe polarization, improving accuracy and longevity. Its waterproof probe enables direct immersion for real-time monitoring. The plug-and-play design with standard connectors ensures easy Arduino integration without soldering. Ideal for hydroponics, aquariums, and water purification systems, this sensor kit includes the analog meter, waterproof probe, and connecting cable, enabling quick deployment for water quality projects.
