DFRobot Gravity Analog TDS Meter Sensor – Waterproof Probe

QAR 95.00/ unit

Description

The DFRobot Gravity Analog TDS Sensor is designed to measure the Total Dissolved Solids (TDS) level in water for quality monitoring applications. It outputs a stable 0–2.3V analog signal compatible with 3.3V and 5V microcontrollers such as Arduino. The module uses an AC excitation source to reduce probe polarization and improve measurement reliability. Equipped with a waterproof probe and Gravity plug-and-play interface, it ensures easy integration into embedded systems. Ideal for water quality testing, hydroponics, and domestic water monitoring systems.
