TrolMaster MBS-PAR Full Spectrum Quantum Sensor | 389-692 nm PPFD

TrolMaster MBS-PAR Full Spectrum Quantum Sensor for Hydro-X PPFD TrolMaster's MBS-PAR is the in-room PPFD sensor that lets a Hydro-X controller dim fixtures based on what is hitting the canopy. Not what the schedule says should be hitting. The full-spectrum quantum element reads 389-692 nm plus/minus 5 nm and captures in micromol/m2/s. It ties back into the controller over a standard RJ12 input. Closed-loop PPFD control is something a clock-driven schedule will never match. Why Closed-Loop PPFD Control Outperforms a Static Schedule Drivers drift. Lamps degrade. Reflective walls get stained over a long flower run. A fixture that delivered 900 micromol/m2/s in week 1 reads closer to 820 by week 14. Growers typically mount the MBS-PAR at canopy height and feed it back to a Hydro-X. The controller nudges dim levels up to hold the target — useful in any room where consistency matters more than a fixed dim percent. Key Features Spectral range: 389-692 nm plus/minus 5 nm — wider than the standard 400-700 nm PAR window for fuller spectrum capture Output: PPFD in micromol/m2/s direct to the Hydro-X controller, not a relative lux number Connector: RJ12 — same plug-and-play hookup as the rest of the TrolMaster sensor family Closed-loop control: Lets the Hydro-X dim fixtures dynamically against a target PPFD instead of a fixed dim percent Cost-effective: More accessible than a lab-grade Apogee while accurate enough for daily controller logic Technical Specifications Specification Value Model MBS-PAR Spectral Range 389-692 nm plus/minus 5 nm Measurement PAR / PPFD in micromol/m2/s Connector RJ12 (Hydro-X / Hydro-X Plus / Hydro-X Pro) Compatibility TrolMaster Hydro-X HCS-1, Hydro-X Plus HCS-3, Hydro-X Pro HCS-2 Use Case Closed-loop PPFD-targeted fixture dimming
