The Story
The DFRobot Gravity Analog TDS Sensor/Meter is an Arduino-compatible kit designed for measuring Total Dissolved Solids (TDS) in water, indicating water cleanliness. It features a wide voltage input (3.3-5.5V) and outputs a 0-2.3V analog signal, making it compatible with both 5V and 3.3V systems. The AC excitation source prevents probe polarization, while the waterproof probe allows for long-term immersion, making it ideal for applications like domestic water testing and hydroponics.
