TrolMaster MBS-TH 3-in-1 Sensor for Hydro-X Replacement Builds
The MBS-TH is the original 3-in-1 sensor that ships with TrolMaster's Hydro-X (HCS-1) controller. Temperature, relative humidity, and ambient light read from one plug-and-play probe. Growers keep this as a backup or after a sensor takes a splash. A Hydro-X room with a dead probe locks out feeding and lighting routines until it is replaced. Comes with a 16 ft RJ12 cable and a T-splitter so a single Hydro-X can run two sensor zones from one input.
Replacement Workflow and Hydro-X Compatibility
Plug-and-play to the original Hydro-X (HCS-1). Unplug the dead probe, plug this in, the controller picks it up. Built-in photocell drives day/night transitions, so light schedules stay in sync with what the room sees. Growers typically mount the probe at canopy height in the center of the room. One important compatibility note. This is the original 3-in-1, not the Hydro-X Pro/Plus 4-in-1. Use the MBS-Pro 4-in-1 for an HCS-2 or HCS-3 controller instead.
Key Features
- Sensor function: 3-in-1 temperature, relative humidity, ambient light in one probe
- Day/night photocell: Built-in light sensor switches the controller's day/night state without a wall clock
- Cable: 16 ft RJ12 with T-splitter — covers a typical 4x8 or 5x10 room from a single Hydro-X
- Output: 0-11.5V signal, max 0.2A draw — does not need an external power adapter
- Operating range: 32-122 F, up to 90% RH — covers a normal indoor grow envelope
