Water Content Sensor 3 with splitter cable set

Check Volumetric Water Content Right at the Sensor

Walking to a controller display just to check one reading gets old fast when a grower wants a quick moisture check while standing in the room. The TrolMaster WCS-3 solves that with a tap-to-wake LCD built directly into the sensor body, showing the current volumetric water content percentage without needing to pull up the controller at all.

It's a 3-prong sensor suited to coir, soil, or rockwool, compatible with the Aqua-X, Aqua-X Plus, Aqua-X Pro, Hydro-X Pro, and Tent-X systems, though how many units each controller supports varies.

Key Features & Benefits

• Tap-to-Wake LCD — shows live VWC% readings right on the sensor body.
• Ultra-Slim Design — fits easily into the grow medium for placement.
• Daisy-Chain Ready — connects multiple sensors together in sequence.
• Mobile Alerts — sends notifications when readings exceed set thresholds.

Who Should Use the WCS-3

Growers practicing crop-steering irrigation, or anyone who wants a fast, on-sensor moisture reading without walking to a controller display, are the intended users of the WCS-3. Its connection limits vary by controller, so check the specific system's supported count before planning a larger sensor array.

About TrolMaster

The on-sensor display on the WCS-3 reflects a practical detail TrolMaster builds into its substrate sensors at the Sacramento, California company's headquarters, letting a grower confirm a reading without walking back to the controller. Supporting five different controller platforms, from the base Aqua-X up through Tent-X, keeps the WCS-3 usable across most of TrolMaster's irrigation-capable systems.

Frequently Asked Questions

Which controllers work with the WCS-3?

The Aqua-X, Aqua-X Plus, Aqua-X Pro, Hydro-X Pro, and Tent-X systems. Connection limits differ by which of those controllers is in use.

How many WCS-3 sensors can I connect to a TCS-1?

Only one WCS-3 can be connected to the TCS-1 controller. Larger controllers such as the NFS-2 or HCS-2 support up to 50.

How do I check a reading on the sensor itself?

Shake or disturb the sensor and the LCD display wakes to show the current VWC% reading. No app or controller access is needed for that quick check.

What's included with the WCS-3?

A water content sensor, an M12 T-splitter, and a 4 ft M12 cable. That covers a standard single-sensor installation.
