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

Read Moisture, Temperature, and EC From One Probe

Tracking substrate conditions with three separate single-purpose probes means three separate insertion points and three cables to manage for what is really one location's data. The TrolMaster WCS-2 combines water content, temperature, and EC sensing into a single five-prong probe, connected to an LCD communication module for on-site reading.

The probe is typically inserted horizontally about a third of the way up from the bottom of a soil or rockwool block, and the free TM+ app displays live readings, historical graphs, and alerts whenever a reading crosses a set threshold.

Key Features & Benefits

• Three-Parameter Sensing — measures water content, temperature, and EC from a single probe.
• On-Module LCD Display — shows live readings directly for easy on-site checks.
• Individual Sensor Addressing — identifies each unit when multiple sensors are connected.
• App-Based Alerts — sends mobile notifications when readings exceed set thresholds.

Who Should Use the WCS-2

Growers running an Aqua-X, Aqua-X Pro, or Hydro-X Pro system who want a detailed, real-time picture of substrate conditions across multiple zones are the intended users of the WCS-2. It's the more capable option for growers who specifically want water content, temperature, and EC in one probe rather than tracking those separately.

About TrolMaster

The WCS-2 represents TrolMaster's next generation of substrate monitoring, developed at the company's Sacramento, California headquarters to fold three separate readings into one probe rather than requiring three separate sensors. Supporting up to 50 units on the NFS-2 or HCS-2 controllers reflects how far a single build can scale with this sensor.

Frequently Asked Questions

Which controllers work with the WCS-2?

The Aqua-X, Aqua-X Pro, and Hydro-X Pro systems specifically. It is not intended for other TrolMaster controller models.

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. Each connected sensor displays its own individual readings.

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. That placement is meant to reflect representative root-zone conditions.

Can I view historical readings?

Yes, the TM+ app stores graphed history for water content, temperature, and EC over time. It also sends alerts whenever a reading crosses a set threshold.
