Gravity TDS Sensor

The Gravity Analog TDS Sensor Meter is a high-performance module designed for measuring the Total Dissolved Solids (TDS) in water, making it ideal for domestic water testing, hydroponics, and aquariums. This sensor works by measuring the conductivity of the water, which correlates to the ion concentration. It features a built-in temperature compensation algorithm to ensure accuracy across varying conditions. Compatible with 3.3V and 5V microcontrollers like Arduino and ESP32, it offers a simple plug-and-play interface via the Gravity connector. The sensor provides an analog voltage output ranging from 0 to 2.3V, corresponding to a TDS range of 0 to 1000ppm. With a compact design and easy calibration process using the DFRobot library, it is an essential tool for DIY electronics enthusiasts and engineers monitoring water quality.
