Analog TDS Meter Water Quality Sensor Module

Analog TDS Meter Water Quality Sensor Module — Overview

The Analog TDS Meter Water Quality Sensor Module is a compact, high-precision device designed to measure Total Dissolved Solids (TDS) in water. By converting dissolved substance concentration into an analog voltage, this sensor delivers accurate, repeatable readings for water treatment, aquaculture, environmental monitoring, and DIY electronics projects.

Key Features

• Accurate TDS Measurement: Advanced sensing technique provides reliable readings for assessing water quality.
• Analog Output: Proportional voltage output that can be read directly by analog input pins on Arduino, Raspberry Pi ADC modules, and other microcontrollers.
• Gravity Connector: Standard Gravity interface simplifies wiring and reduces setup time with compatible boards and modules.
• Wide Measurement Range: Typically measures 0 to 1000 ppm, suitable for drinking water, aquaponics, and industrial monitoring.
• Easy Calibration: Quick calibration using common TDS standard solutions to improve accuracy for your specific water type.
• Durable Design: Robust construction for consistent performance in typical lab and field conditions.
