Fixed wall-mount bracket for TrolMaster MBS-PRO and MBS-K30 sensors — 2-pack.
The TrolMaster TSB-1 Sensor Bracket is a dedicated wall-mount solution designed specifically for the MBS-K30 and MBS-PRO sensor housings, keeping sensors locked in a fixed, repeatable position instead of hanging loose in the canopy zone. Sold as a 2-pack with a mortise-and-tenon connection system that allows multiple holders to link together.
The TSB-1 is a purpose-built wall-mount bracket for TrolMaster's MBS-K30 CO2 sensor (used with the Carbon-X platform) and the MBS-PRO 4-in-1 environmental sensor (used with the Hydro-X controller family). Each TSB-1 package ships as a 2-pack, giving you two brackets per order.
The bracket features a curved-edge profile that conforms precisely to the MBS sensor body, creating a tight, secure lock once seated. This eliminates the common installation problem of sensors left to hang freely on their RJ12 cable runs — a situation that introduces positional variability and creates cable strain at the connector point over time.
Multiple TSB-1 holders can be joined to each other using a mortise-and-tenon joint, allowing you to gang brackets together on the same wall section when you need multiple sensor positions in close proximity.
Any licensed indoor cultivation facility running TrolMaster's Hydro-X or Carbon-X control systems will encounter a situation where MBS-PRO or MBS-K30 sensors need to be fixed at a specific, repeatable location — canopy height, intake zones, multi-room CO2 monitoring points, or compliance-mandated sensor positions required by local AHJ.
For commercial facilities with multiple rooms or zones, the TSB-1 provides a consistent, professional sensor installation that holds calibration position across grow cycles. When sensors move between runs — shifted by airflow, accidentally bumped, or retaped — readings drift and controller logic responds to position artifacts rather than true environmental conditions.
The TSB-1 is also the right solution for operators using two MBS-K30 sensors per Carbon-X zone to meet local code redundancy requirements. Fixed bracket positions ensure both sensors remain where they were commissioned, not where gravity and cable tension pull them.
The curved-edge design is contoured to match the MBS sensor housings directly — it is not a generic clip or zip-tie workaround. The sensor seats and locks without tools, but holds position securely once mounted.
The mortise-and-tenon joining system lets you connect multiple brackets in-line on the same mounting surface. This is useful in greenhouse or multi-light-bay applications where you want adjacent sensor positions without running separate wall anchors for each bracket.
Installation is straightforward: mount the bracket to the wall surface, seat the MBS sensor body into the bracket until it clicks, and route the RJ12 cable to the nearest hub or controller port. No special wiring or adapters are required beyond the standard RJ12 cable already included with each TrolMaster sensor.
In a properly commissioned TrolMaster environmental control setup, sensor placement is a deliberate decision — canopy height, centered horizontally in the zone, away from intake ports and exterior walls. Once that position is dialed in, the TSB-1 holds it indefinitely. The bracket converts a calibration decision into a physical constant.
For Carbon-X CO2 safety systems — where each monitored zone may require one or two MBS-K30 sensors to meet local code — the TSB-1 provides the fixed mounting that ensures sensors stay at the specified monitoring height across all rooms and all cycles.
Order quantity scales simply: one TSB-1 (2-pack) covers two sensor positions. Map your room count and sensors-per-room, and size the bracket order accordingly. The TSB-1 is available through HSC alongside the full TrolMaster sensor and controller catalog — quote all line items together to consolidate your order.

The TSB-1 is specifically designed for two TrolMaster sensor housings: the MBS-K30 (the NDIR CO2 sensor for the Carbon-X platform) and the MBS-PRO (the 4-in-1 temp/humidity/CO2/light sensor for the Hydro-X controller family). It is not a universal bracket and is not designed to fit other TrolMaster sensor models.
Each TSB-1 package contains 2 brackets. If you need to cover multiple sensor positions across multiple rooms or zones, order one TSB-1 per two sensor positions required.
Yes. TrolMaster designed the TSB-1 with a mortise-and-tenon joint so that more than one holder can be connected together. This is useful when you want to mount adjacent sensors at the same wall location without requiring separate anchor points for each bracket.
TrolMaster controllers respond to real-time sensor readings to drive HVAC, CO2, and lighting device stations. If a sensor is hanging freely on its cable, airflow, maintenance traffic, or physical contact can shift its position between runs — introducing positional drift in temperature, humidity, and CO2 readings. A fixed bracket keeps the sensor at the calibrated measurement point, so controller logic is responding to actual zone conditions rather than positional artifacts.
The TSB-1 is not itself a compliance component, but local AHJs and fire codes that require fixed CO2 sensor positions in enriched grow environments effectively require a fixed-mount solution like the TSB-1. If your jurisdiction specifies that sensors must be mounted at a defined height and location, a free-hanging sensor on an RJ12 cable will not satisfy that requirement. Confirm your local code requirements with your AHJ.
