The TrolMaster WCS-1 is a three-prong volumetric water content (VWC) sensor designed specifically for the Aqua-X NFS-1 irrigation control system. It measures 0–100% substrate water content directly in soil, coco coir, or rockwool, providing live readings to the sensor's LCD, Aqua-X controller, and TrolMaster app. The data can be used to monitor dry-back conditions and support condition-based irrigation rather than relying solely on fixed timers.

Key Advantage: The WCS-1 provides direct root-zone moisture data for condition-based irrigation, allowing growers to track actual substrate dry-back rather than relying exclusively on scheduled watering. Its ability to connect up to 8 sensors to one Aqua-X also allows multiple zones, tables or growing areas to be monitored through a single controller.
