Description

This sensor operates on the principle of electrical conductivity to estimate Total Dissolved Solids (TDS) in a solution. It uses a pair of electrodes within the probe; an applied AC signal minimizes electrode polarization, and the measured conductivity is correlated to TDS levels. The integrated signal conditioning circuit provides a stable 0-2.3V analog output proportional to the measured concentration.

Designed for integration into water quality monitoring systems, the probe features a sealed 6.35mm diameter body suitable for direct immersion. The 1/4″ plug connector ensures a reliable electrical connection. It is intended for use in applications requiring monitoring of water purity, such as in filtration systems, hydroponics, and aquariums, over an extended service life.

Key Features

  • 0-3000 ppm TDS measurement range for comprehensive water quality assessment.
  • High ±2% measurement accuracy ensures reliable data for system control.
  • Broad 3.3V to 5V DC input voltage compatibility for flexible system integration.
  • Standard 0-2.3V analog output signal for direct microcontroller ADC connection.
  • Compact 6.35mm diameter probe with robust, leak-proof housing.
  • Quick-connect 1/4" PE plug simplifies installation and maintenance.
  • Optimized performance-to-cost ratio for embedded and industrial monitoring projects.

Applications

  • Reverse Osmosis (RO) and pure water machine purity monitoring and filter life indication.
  • Hydroponic and aquaponic nutrient solution concentration monitoring.
  • Aquarium water quality management and automated dosing system control.
  • Industrial process water and cooling tower TDS level monitoring.
  • Portable water quality testing equipment and environmental sensing nodes.

Frequently Asked Questions

What is the operating voltage range for this TDS sensor?

The sensor supports a wide input voltage range from 3.3V to 5V DC, making it directly compatible with most microcontroller platforms like Arduino (5V), Raspberry Pi (3.3V), and ESP32 (3.3V) without requiring a level shifter.

How do I interface this probe with an Arduino?

Connect the probe's output wire to an Arduino analog input pin (e.g., A0). The sensor provides a 0-2.3V analog signal corresponding to 0-3000 ppm. Use the analogRead() function and map the value to ppm using a calibration formula or lookup table provided in the datasheet.

Does this sensor require calibration?

For accurate absolute measurements, calibration using a standard TDS solution is recommended. The sensor provides a linear output, but factors like temperature can affect conductivity. For relative measurements or trend monitoring, it can be used directly with the factory calibration.
