Full Spectrum Quantum Sensor

Let Hydro-X Auto-Adjust Light Output From One Sensor

Holding a target light intensity by feel or a fixed dimmer setting drifts over time as fixtures age or canopy height changes, which is where a feedback sensor earns its keep. The TrolMaster MBS-PAR Full Spectrum Quantum Sensor measures photosynthetically active radiation from any light source used to grow plants, with a spectral range of 389 to 692nm, plus or minus 5nm, and improved spectral response for more accurate LED measurements.

Paired with a Hydro-X controller, the sensor lets the system automatically raise or lower supplemental lighting output to continuously hold the exact PPFD level selected, removing the need for manual adjustments as conditions change.

Key Features & Benefits

• Full-Spectrum PAR Measurement — covers 389 to 692nm with improved LED measurement accuracy.
• Automatic Light Adjustment — works with Hydro-X to hold a target PPFD level automatically.
• Onsite Reading — displays measurements directly without extra software.
• Plug and Play Setup — connects to a Hydro-X controller without complex configuration.

Who Should Use the TrolMaster MBS-PAR Sensor

Growers running a Hydro-X controller who want supplemental lighting to adjust automatically based on real PPFD readings, instead of a fixed schedule that ignores fixture drift or canopy changes, are the intended users. It suits both single-room and multi-zone setups where consistent light intensity matters.

About TrolMaster

The MBS-PAR feeds real-time light data back into TrolMaster's Hydro-X control loop, a closed-loop approach the Sacramento, California company applies to lighting the same way its climate sensors drive HVAC and humidity equipment. It reflects how directly the company ties sensor data to automated equipment response.

Frequently Asked Questions

What spectral range does the MBS-PAR cover?

389 to 692nm, plus or minus 5nm, with improved accuracy for LED measurements. That range covers the photosynthetically active portion of the light spectrum.

What does this sensor do when paired with Hydro-X?

It lets the controller automatically raise or lower supplemental lighting to hold the PPFD level selected. No manual dimmer adjustments are needed once a target is set.

What's included with the sensor?

A 1/2-inch post clamp, a 4ft RJ12 cable, an RJ12 T-splitter, and two 1/2-inch end caps. These cover a standard mounting and connection setup.

How is the MBS-PAR mounted?

With the included 1/2-inch post clamp and end caps, typically at or near canopy height. That hardware covers a standard mounting setup without needing separate brackets.

Does the sensor require complex setup?

No, it uses a plug-and-play connection to the Hydro-X controller. Once mounted and connected, the target PPFD level is set through the controller itself.
