The TrolMaster WCS-3 Water Content Sensor 3 is an advanced moisture sensor designed to measure the volumetric water content (VWC) in the growing medium in real time.
The TrolMaster WCS-3 Water Content Sensor 3 is an advanced moisture sensor designed to measure the volumetric water content (VWC) in the growing medium in real time. Thanks to its high accuracy and ease of use, the WCS-3 allows you to optimise irrigation cycles and improve water management in greenhouses and indoor and outdoor growing systems.
Compatible with the Aqua-X (NFS-1), Aqua-X Plus (NFS-3), Aqua-X Pro (NFS-2), Hydro-X Pro (HCS-2), Green-X (GCS-1) and Tent-X (TCS-1) controllers, the WCS-3 sensor offers complete integration into the TrolMaster automation system.
How it works
Each WCS-3 sensor is equipped with 3 sensing tips that are inserted directly into the substrate - such as coco, soil or rockwool - to accurately measure moisture in percentages. The integrated LCD display shows the VWC% value in real time and is automatically activated by a simple touch or movement of the sensor.
Multiple WCS-3 sensors can be connected to a single controller:
Up to 50 sensors on NFS-2 and HCS-2
Up to 20 sensors on NFS-3
Up to 8 sensors on NFS-1
Only 1 sensor on TCS-1
(Note: TCS-1 supports one WCS-3 only).
