Soil Moisture, Temp and EC 3-in-1 Sensor with cable set

Monitor Substrate Moisture, Temperature, and EC in Real Time

The TrolMaster WCS-2 is part of the next generation of substrate monitoring, measuring water content percentage, temperature, and EC directly in your grow media.

A five-prong sensor assembly connects to an LCD communication module, and is typically inserted horizontally about a third of the way up from the bottom of your soil or rockwool block.

Through TrolMaster's free TM+ app, you can view live readings, historical data graphs, and receive notifications whenever a WCS-2 reading exceeds your alarm settings.

Key Features & Benefits

• LCD Display — Shows live readings directly on the module for easy on-site checks.
• Addressing Button — Identifies each sensor individually when multiple units are connected.
• Three-Parameter Sensing — Measures water content, temperature, and EC from a single probe.
• App Alerts — Sends mobile notifications when readings exceed your set thresholds.

Who Should Use the WCS-2

Growers running an Aqua-X, Aqua-X Pro, or Hydro-X Pro system who want a clear, real-time picture of substrate conditions across multiple zones will get the most out of the WCS-2.

Connecting Multiple Sensors

Up to 50 WCS-2 sensors can be connected to the NFS-2 or HCS-2 controllers, while the NFS-1 controller supports up to 8 sensors, each displaying its own readings.

Frequently Asked Questions

Which controllers work with the WCS-2?

The WCS-2 is designed specifically for the Aqua-X, Aqua-X Pro, and Hydro-X Pro systems and is not intended for other controllers.

How many sensors can I run at once?

Up to 50 on the NFS-2 or HCS-2 controllers, or up to 8 on the NFS-1 controller.

Where should the sensor be placed?

Insert the five-prong probe horizontally about a third of the way up from the bottom of the grow media container or block.

Can I view historical readings?

Yes. The TM+ app stores graphed history for water content, temperature, and EC over time.
