THROUGH THE Cultivator's LENS Hands-On Evaluation

Who This Is For

  • You are adopting crop steering because visual checks alone cannot accurately time your dry-back periods.
  • You are adding multi-zone monitoring because testing pots by hand is too slow for a high-density facility.

What We Found

  • The onsite LCD is the real winner here since you can check stats at the plant without pulling out your phone.
  • We find the multi-zone addressing saves huge amounts of time when you need to track different zones on one system.
  • The WCS-2 is more durable than the older probes we have seen, especially in high-humidity greenhouse environments.

What Users Say

  • Users who switched from visual checks say they stopped overwatering because they now have hard data on root saturation.
  • Operators who set up mobile alerts say they caught pump failures before the crop suffered any permanent damage.

TrolMaster WCS-2 3-in-1 Water Content Sensor | Precision Substrate Monitoring

The WCS-2 provides real-time data for water content, temperature, and electrical conductivity within the growing medium. This substrate sensor integrates with the Aqua-X Control System to enable precise crop steering, a technique where growers manipulate irrigation to influence plant development. TrolMaster designed this unit for intermediate growers who require immediate feedback on root zone conditions to prevent crop loss.

In Detail

TrolMaster WCS-2 Application View

The WCS-2 utilizes a multi-parameter probe to track the three most critical variables in the root zone simultaneously. By monitoring electrical conductivity (EC), which measures the concentration of dissolved salts in the medium, growers can ensure nutrient strength remains within the target range. The sensor communicates directly with the Aqua-X controller to log historical data and trigger automated irrigation events based on moisture depletion levels.

  • Real-time measuring of water content, temperature, and EC of the growing medium.
  • Alarm and mobile notifications alert you immediately when setpoints are exceeded.
  • LCD display provides an onsite readout for quick manual checks.
  • Addressing button simplifies the process of assigning the sensor to the control system.
  • USB port ensures reliable connectivity to the master controller.

Features

Real-Time Monitoring

The sensor tracks WC, EC, and temperature constantly to provide a live snapshot of root zone health.

Mobile Notifications

Integrated alerts send push notifications to your smartphone if moisture or nutrient levels drift outside your parameters.

On-Board LCD

A built-in digital screen allows for immediate onsite verification without checking the master controller or app.

Addressing Button

The dedicated button allows for rapid sensor identification and configuration within the Aqua-X ecosystem.

Frequently Asked Questions

How do I ensure the sensor remains calibrated?

The WCS-2 is factory calibrated but requires proper placement to maintain accuracy. Ensure the probes are in full contact with the medium and avoid air pockets which can cause false dry readings.

Will I receive notifications if the moisture level drops while I am away?

Yes, the sensor triggers mobile notifications through the Aqua-X system. You will receive an alert on your smartphone if the water content or EC exceeds your defined setpoints.

Can I use this sensor with other control systems?

The WCS-2 is specifically designed for compatibility with the TrolMaster Aqua-X Control System. It utilizes a proprietary connection to communicate data to the master controller.

Does high nutrient strength affect the moisture reading?

The sensor measures EC and water content independently to provide accurate data even in high-salt environments. This allows you to monitor nutrient buildup without skewing your irrigation data.

What is the simplest way to set up the sensor?

Connect the sensor to the Aqua-X controller via the USB port and press the addressing button on the sensor unit. The controller will automatically recognize the device for immediate monitoring.
