Analog TDS Sensor/ Meter for Arduino

The Analog TDS Sensor Meter for Arduino is a reliable and easy-to-use module designed to measure the Total Dissolved Solids (TDS) in water. It helps determine water purity by detecting dissolved ions such as salts, minerals, and metals.

This sensor provides an analog voltage output, making it simple to interface with Arduino, ESP8266, ESP32, and other microcontrollers. It is widely used in water quality monitoring systems, hydroponics, aquariums, and drinking water analysis.

The module ensures stable and accurate readings when used with proper calibration and temperature compensation. Its plug-and-play design allows quick integration into DIY and IoT projects.

Whether you’re building a smart water monitoring system or testing water quality, this TDS sensor is an essential tool for reliable measurement.
