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 s...
