THROUGH THE Cultivator's LENS Hands-On Evaluation

Who This Is For

  • You are adding a dedicated greenhouse sensor because your current setup fails to account for changing cloud cover.
  • You are upgrading to the Green-X line because you need a system that triggers mode changes based on real light levels.
  • You are consolidating your sensing layer because managing separate meters for CO2 and humidity is eating your time.

What We Found

  • The built-in photocell is the real reason to get this since it lets the room react to actual light instead of a clock.
  • We liked the SD slot for troubleshooting because it lets you pull high-resolution data logs when the Wi-Fi is spotty.
  • Having the display on the sensor itself is a lifesaver when you just want a quick reading without pulling out a phone.

What Users Say

  • Growers who switched to this sensor say the automatic day and night transitions stopped their CO2 from wasting at dusk.
  • Users who added these to every zone say the RJ12 daisy-chaining made the initial wiring much faster than expected.
  • Operators who export the SD data report they finally caught the humidity spikes that were happening during shift changes.

TrolMaster Green-X MBS-GH Greenhouse Control

Maintaining a stable environment is the most critical factor in successful greenhouse cultivation. The TrolMaster Green-X MBS-GH 4-in-1 Sensor acts as the eyes and ears of your TrolMaster Green-X GCS-1 Greenhouse Control system, ensuring that your plants always have the optimal conditions they need to thrive. By providing precise, real-time data on four essential environmental variables, this sensor allows for the high-level precision required in modern greenhouse control setups.

Beyond simple monitoring, the MBS-GH features an integrated photocell that detects actual light levels to automatically trigger day and night modes. This eliminates the need for manual scheduling and allows your climate programs to respond dynamically to the sun. Whether you are replacing an existing unit or setting up a new zone within the TrolMaster Green-X ecosystem, the MBS-GH delivers the reliability and accuracy professional growers demand.

FAQs

What does the MBS-GH sensor measure?+

The MBS-GH simultaneously monitors four indoor environmental parameters: air temperature, relative humidity, CO₂ PPM, and ambient light levels via a built-in photocell.

What does the built-in photocell do?+

The photocell detects actual ambient light conditions inside the greenhouse and signals the GCS-1 to switch between day and night operating modes accordingly.

Is the MBS-GH a direct replacement for the sensor included with the GCS-1?+

Yes, the MBS-GH is the same 4-in-1 sensor that ships with the GCS-1 Greenhouse Control System and is sold separately as a replacement unit.

Can I save or export the environmental data the MBS-GH collects?+

Yes. The MBS-GH features a backlit 128×128 LCD display with button controls and Micro SD card support for data logging and export.

How many MBS-GH sensors can I connect to a single GCS-1?+

The GCS-1 supports a maximum of one MBS-GH sensor per set. For additional monitoring, the GCS-1 ecosystem offers other compatible supplemental sensors.

What operating conditions is the MBS-GH rated for?+

The MBS-GH is rated for use in temperatures from 32°F to 122°F (0–50°C) and humidity levels up to 95% RH.
