Master Your Water Quality: A Guide to the Graylogix Analog TDS Sensor for Arduino

Introduction Total Dissolved Solids (TDS) is a key indicator of water cleanliness, representing the concentration of dissolved minerals, salts, and metals. While handheld TDS pens are common, they don’t allow for automation or long-term data logging. That’s where the Graylogix Analog TDS Sensor comes in.



Why Choose This Sensor?

  • Plug-and-Play Simplicity: Designed for Arduino, it requires no soldering and works right out of the box.

  • Wide Compatibility: Supports 3.3V to 5.5V input, making it compatible with Arduino, ESP32, and Raspberry Pi.

  • Durable & Stable: Features a waterproof probe and an AC excitation source that prevents probe polarization, extending its lifespan significantly.

  • Real-Time Monitoring: Unlike manual pens, this sensor can stay submerged for continuous data tracking.

Applications

  • Hydroponics: Ensure your plants get the exact nutrient concentration they need.

  • Aquariums: Keep your aquatic life safe by monitoring mineral spikes.

  • Home Automation: Build your own smart water purifier that alerts you when filters need changing.

Conclusion For just ₹290, this sensor bridges the gap between hobbyist DIY and professional water analysis. Check it out at Graylogix.
