Who This Is For
- You are replacing your main sensor because the old one is drifting and causing erratic humidity spikes.
- You are adding a second sensor because your tent has a micro-climate where heat pockets build up near the far wall.
What We Found
- Keeping a spare sensor in the drawer is a smart move since a failure can stall your entire climate setup.
- That 16ft cable gives you enough slack to mount the sensor right in the middle of the canopy for better data.
- Most people overlook the light sensor, but it is what actually triggers your controller's night mode.
What Users Say
- Environment charts became more stable and predictable for everyone who replaced their aging sensors.
- Using the light sensor to trigger day and night modes meant people stopped making manual timer adjustments.
TrolMaster MBS-TH Temperature, Humidity & Light Sensor
Maintaining a stable environment is critical for high-yield harvests, but a faulty sensor can lead to catastrophic climate shifts. The TrolMaster MBS-TH is a high-precision 3-in-1 sensor designed for growers who demand total accuracy in their environmental controllers. Whether you are managing a large-scale facility or a small grow tent, this sensor ensures your TrolMaster Hydro-X HCS-1 Grow Tent Control receives the precise data it needs to regulate temperature and humidity levels effectively.
Designed as a direct replacement for original equipment, the MBS-TH eliminates the risk of climate fluctuations caused by aging or damaged sensors. By monitoring temperature, relative humidity, and ambient light, it allows your system to automatically transition between day and night cycles, providing the consistent greenhouse control necessary for plant health and vigor. Installation is seamless, allowing you to restore your TrolMaster system to peak performance in minutes.
Compatibility: TrolMaster Hydro-X and Tent-X Systems

TrolMaster backs the MBS-TH with a 3-year warranty from the original date of purchase, covering all mechanical and electronic components under normal operating conditions. Components that fail due to abnormal or improper usage are excluded from this coverage.
FAQs
The MBS-TH simultaneously tracks three key variables: ambient temperature, relative humidity, and light levels. This data is transmitted to your controller to trigger automated responses such as turning on fans, AC units, or dehumidifiers.
Yes, the MBS-TH is the official OEM replacement sensor for the TrolMaster Hydro-X and Tent-X controllers, using the same RJ12 connection as the original sensor.
The light sensor allows the controller to detect day and night cycles. This enables the system to automatically switch between different environmental setpoints for daytime and nighttime growing conditions.
It should be mounted at canopy height in a central location. Avoid placing it directly in front of fans, humidifiers, or intense light hotspots to ensure the readings are representative of the whole room.
No. While it can handle high humidity (up to 90%), the sensor must be kept dry. Avoid spraying water or nutrients near the sensor to prevent damage to the electronic components.
