Description

The Seeed Studio Industrial EC & TDS Sensor is a high-performance solution for real-time liquid analysis in harsh environments. By integrating Electrical Conductivity (EC), Total Dissolved Solids (TDS), and Temperature sensing into a single probe, it provides a comprehensive profile of water quality. The sensor features graphite electrodes and internal temperature compensation, ensuring stable and accurate readings even as environmental conditions fluctuate. Housed in a durable IP68 enclosure, it is designed for long-term immersion in industrial wastewater, hydroponic nutrients, and environmental monitoring sites.

Advanced Liquid Analytics

Temperature Compensation Built-in NTC sensor automatically adjusts EC/TDS readings based on liquid temperature for consistent accuracy.
Modbus RTU Integration Standard RS485 interface allows for easy connection to data loggers, PLCs, or LoRaWAN Modbus DTUs.
Anti-Corrosion Probe Features high-quality graphite electrodes that resist polarization and chemical corrosion in liquid environments.
Standard Signal Output Supports easy EC calibration through software commands or onboard buttons to maintain measurement fidelity.

Industrial Use Cases

Hydroponics & Smart Farming: Monitor nutrient solution concentration to ensure optimal plant growth and yield.
Environmental Monitoring: Track water quality in rivers, lakes, and coastal areas for ecological research.
Industrial Wastewater: Monitor the salt content and chemical composition of process water in manufacturing plants.

Technical Integration

The sensor operates on a wide 3.6V to 30V DC power supply and provides a robust RS485 Modbus RTU output. For remote monitoring, it can be paired with the SenseCap series of LoRaWAN transmitters. The probe includes a 5-meter cable (customizable) and supports varied installation methods including immersion or pipe-flow mounting.
