TrolMaster Water Content Sensor 3 with Splitter Cable Set (WCS-3)
Real-Time Volumetric Water Content (VWC) Monitoring for Precision Irrigation & Crop Steering
The TrolMaster WCS-3 Water Content Sensor 3 is a high-precision Volumetric Water Content (VWC) sensor designed to measure the moisture level of grow media in real time. Using a rugged 3-prong probe, the WCS-3 provides accurate percentage-based readings of water content in substrates such as coco coir, soil, peat, and rockwool, giving growers granular insight into their irrigation cycles and root-zone moisture dynamics.
Compatible with major TrolMaster controllers—including Aqua-X (NFS-1), Aqua-X Pro (NFS-2), Aqua-X Plus (NFS-3), Hydro-X Pro (HCS-2), and Tent-X (TCS-1)—the WCS-3 is a critical tool for precision irrigation, crop steering, and environmental automation. With support for daisy-chaining multiple sensors, growers can measure moisture across multiple zones or root-level depths with ease.
Each sensor includes a tap-to-wake LCD display, which activates when the probe is lightly shaken, allowing growers to instantly view the current VWC % directly on the sensor—no controller or external device required.
Smart Integration & Scalable Sensor Networks
Connect multiple WCS-3 sensors to a single controller to build a complete irrigation monitoring network:
- Up to 50 sensors on NFS-2 (Aqua-X Pro) & HCS-2 (Hydro-X Pro)
- Up to 20 sensors on NFS-3 (Aqua-X Plus)
- Up to 8 sensors on NFS-1 (Aqua-X)
- 1 sensor on TCS-1 (Tent-X)
Note: TCS-1 supports only one WCS-3 sensor.
Real-time VWC measurements can trigger alarms and mobile notifications when user-defined moisture thresholds are exceeded—ensuring consistent irrigation, protecting root health, and preventing under- or over-watering.
