Description
Accurate temperature, humidity and light data for Hydro-X
The TrolMaster MBS-TH 3-in-1 Sensor is a replacement or spare environmental sensor for the Hydro-X control system, measuring temperature, humidity and light inside a grow tent or room. It feeds the real-time data your controller needs to run fans, heaters, humidifiers and dehumidifiers correctly, and its built-in photocell detects day and night cycles so the system can apply different climate strategies when lights are on or off.
What's Included
- 3-in-1 temperature / humidity / light sensor
- 16 ft RJ12 cable
- RJ12 T-splitter
Key Benefits
- All-in-one sensor measuring temperature, humidity and light in one unit
- Built-in photocell automatically detects day and night lighting cycles
- Plug-and-play RJ12 connection to any Hydro-X controller
- Stable environmental control for grow tents and grow rooms
- Protects nutrient uptake, root health and yield by catching temperature and humidity swings early
- Direct replacement or spare for existing Hydro-X systems
Fixing gaps in your environmental data
Undetected swings in temperature or humidity stress plants, slowing vegetative growth, weakening roots and raising the risk of mould and mildew in flower. The MBS-TH continuously reports live readings to the Hydro-X controller so it can adjust equipment automatically, keeping conditions stable across day and night through the whole grow cycle.
How to Use
- Mount the sensor at canopy height inside the tent or room for accurate readings.
- Connect it to the Hydro-X controller with the supplied 16 ft RJ12 cable.
- Use the RJ12 T-splitter if adding further sensors or modules.
- Keep the sensor dry and clean, and avoid spraying water or nutrients directly onto it.
