TrolMaster WCS-9 Substrate Sensor Set (VWC, EC & Temp)

The TrolMaster WCS-9 Substrate Sensor is a 3-in-1 device designed for the Aqua-X, Hydro-X, Tent-X, and Green-X Control Systems (NFS-1, NFS-2, NFS-3, HCS-2, TCS-1, GCS-1). Represents the pinnacle of the WCS series, engineered to deliver unparalleled precision in monitoring both traditional soil and high-bulk EC soilless substrates. Recognizing the inherent limitations of single-sensor monitoring—which can frequently misrepresent the root zone due to localized anomalies like "hot spots" or water channeling—the WCS-9 introduces an advanced, completely redesigned internal multi-node architecture. Features Precision Measurement Data Aggregation Advanced Daisy-Chain Connectivity Dynamic Reading Intervals Simplified Calibration "Feed on Demand" Control Affordable Scalability & Free App Access This innovative framework permits the daisy-chaining of up to four individual Sensor Nodes directly into a single Sensor Display. By aggregating data across multiple points in the growing medium, the system calculates and provides a highly accurate and trustworthy average of the root zone's Volumetric Water Content (VWC), Electrical Conductivity (EC), and Temperature. By providing hyper-accurate, verified root zone data, the WCS-9 serves as the crucial mechanism for TrolMaster’s advanced "Feed on Demand" irrigation strategy. This sensor-based control replaces traditional timer-based guessing by utilizing real-time moisture parameters to automatically trigger irrigation events, allowing cultivators to execute precise dry-backs and sophisticated crop steering strategies effortlessly. Users can monitor the water content, temperature, and EC on their smartphone using TrolMaster's free TM+ Pro App. The app also allows viewing historical data graphs and receiving notifications if sensor readings exceed customised high or low alarm settings.
