Analog TDS Sensor Module

The Analog TDS Sensor Module is a commonly used module for measuring Total Dissolved Solids (TDS) in water — an important parameter for assessing water quality, purity, and salinity. It’s often used in hydroponics, aquariums, environmental monitoring, and water filtration systems.

Features:

Wide Voltage Input: 3.3~5.5V
Good Compatibility Output: 0~2.3V analog signal output, compatible with 5V or 3.3V controller
AC Excitation Source: effectively prevent the probe from polarization
Waterproof Probe
Easy to Use: Arduino compatible, simple connection, plug, and play without soldering
