Water Content Sensor with Cable Set

Fine-Tune Irrigation With Real Substrate Moisture Data

Watering on a fixed timer ignores what's actually happening inside the growing medium, which can mean over- or under-watering as conditions shift. The TrolMaster WCS-1 Water Content Sensor measures the percentage of water and nutrients actually held in the growing medium, reporting real-time readings on the sensor module itself, an Aqua-X controller, and the TrolMaster app.

Up to eight sensors can connect to a single controller at once, with readings averaged across zones to help growers fine-tune irrigation timing based on substrate conditions rather than the clock.

Key Features & Benefits

• Real-Time Moisture Readings — measures water and nutrient percentage in growing medium directly.
• RJ12 Cable Connection — links the sensor to a compatible Aqua-X controller.
• Connects Up to 8 Sensors — monitors multiple zones from one controller at once.
• Multi-Location Display — shows readings on the module, the controller, and the app.

Who Should Use the WCS-1 Water Content Sensor

Growers who want to fine-tune irrigation timing around actual substrate moisture, instead of a fixed watering schedule that ignores real conditions, are the intended users of the WCS-1. Running several sensors across zones gives a fuller picture than relying on a single reading for an entire room.

About TrolMaster

The WCS-1 brings substrate-level feedback into TrolMaster's Aqua-X irrigation platform, developed at the company's Sacramento, California headquarters so watering decisions can be based on the growing medium itself rather than a clock. Displaying readings on the module, the controller, and the free TM+ app keeps that data available wherever a grower happens to be checking it.

Frequently Asked Questions

How many sensors can connect to one controller?

Up to 8 Water Content Sensors. Readings from multiple sensors can be averaged together to guide irrigation timing.

What does this sensor measure?

The percentage of water and nutrients held in growing medium. It reports that reading directly rather than an indirect proxy.

How does this sensor connect to the controller?

Through a standard RJ12 cable connection. No separate power supply is needed beyond that link.

Where can I view sensor readings?

On the sensor module itself, an Aqua-X controller, and the TrolMaster app. All three locations show the same underlying data.
