Temp/Humid/CO2/Light 4-in-1 Sensor for Hydro-X Pro & Plus

Cover More Ground With Multi-Point Environmental Sensing

A single sensor placed in the middle of a large or unevenly conditioned room can miss real variation between zones, which is exactly the gap the MBS-PRO is built to close. The TrolMaster MBS-PRO combines a precision air temperature, humidity, and CO2 sensor with a photocell in one water-resistant, injection-molded enclosure built for Hydro-X Pro and Hydro-X Plus systems.

Because up to 50 sensors can be connected to the Hydro-X Pro, multiple MBS-PRO units can be placed throughout the growing area, with readings either averaged together or assigned individually to control a specific zone.

Key Features & Benefits

• Plug & Play — connects directly into a Hydro-X Pro or Plus system.
• Built-In LCD — displays live readings on-site without needing the controller nearby.
• Push-Lock Connection — simplifies installation and keeps cabling secure.
• Multi-Point Coverage — supports up to 50 sensors per Hydro-X Pro system for zone-specific control.

Who Should Use the MBS-PRO

Growers managing larger or multi-zone spaces who need spot readings from several locations, rather than a single average for the whole room, will find the MBS-PRO well suited to that kind of layout. It's built for the higher sensor counts the Pro and Plus controllers support.

About TrolMaster

The MBS-PRO extends multi-point sensing to TrolMaster's higher-tier Hydro-X Pro and Plus controllers, engineered at the Sacramento, California company's headquarters to support the larger sensor counts those systems allow. Zone-specific readings like this are part of what separates the Pro and Plus tiers from the base HCS-1 controller.

Frequently Asked Questions

Does the MBS-PRO need extra power?

Yes, it requires the SPH-1 powered splitter hub for supplemental power. It is not designed to run on standard controller cable power alone.

How many MBS-PRO sensors can I run?

Up to 50 sensors can be connected to the Hydro-X Pro controller. The Plus controller supports a smaller maximum, so check that system's specification before planning a large sensor count.

Can I use one reading to control multiple devices?

Yes, sensor readings can be averaged together or used individually to control a specific zone. That flexibility depends on how the controller is configured.

What does the built-in LCD show?

The current temperature, humidity, CO2, and light conditions at that sensor's location. No separate app is needed to check a quick on-site reading.
