TDS Meter V1.0 Water Quality Sensor Module 3.3V-5V

The TDS Meter V1.0 Water Quality Sensor Module is an easy-to-use development board designed to measure the Total Dissolved Solids (TDS) levels in water. TDS indicates how many milligrams of soluble solids are dissolved in one liter of water, serving as a key indicator of water purity. Operating on a wide input voltage range of 3.3V to 5.5V, this analog sensor module is highly compatible with popular 5V and 3.3V control systems, making it a perfect choice for makers, students, and engineers looking to integrate water quality testing into their projects.

This module outputs an analog signal (0 to 2.3V) that corresponds linearly to the TDS value of the water, allowing for simple calibration and interfacing with microcontrollers like Arduino, ESP32, Raspberry Pi Pico, and STM32. It is widely used in domestic water quality monitoring, hydroponics, aquariums, and DIY water filtration systems. With its plug-and-play design and onboard signal conditioning, you can quickly build a reliable water monitoring station without complex external circuitry.

Features:

• Wide Voltage Input: Supports 3.3V to 5.5V DC, making it directly compatible with both Arduino (5V) and ESP32/Raspberry Pi (3.3V) platforms.
• Analog Signal Output: Provides a filtered, stable analog voltage output from 0V to 2.3V for easy ADC sampling.
• High Measurement Range: Capable of measuring TDS levels from 0 to 1000ppm, suitable for standard drinking water and hydroponic nutrient solutions.
• Standard Connectors: Features a 3-pin JST-type connector for power and signal output, and a 2-pin connector for the TDS probe connection.
• Compact Form Factor: Small PCB footprint with four integrated mounting holes for easy installation in custom enclosures.
