Description
A precision sensor designed to measure the Total Dissolved Solids (TDS) level in water — that is the Arduino TDS Water Conductivity / Water Quality Sensor Module. By detecting the electrical conductivity of the liquid, the sensor estimates the concentration of dissolved substances such as salts, minerals, nutrients, and other impurities, providing a useful indication of water quality. This module consists of a signal conditioning board and a waterproof probe. The probe is placed in the water, and the module outputs an analog voltage proportional to the measured TDS level. It is fully compatible with Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller platforms. The sensor operates from 3
