£47.95

The TrolMaster MBS-TH is the replacement 3-in-1 environmental sensor for the Hydro-X HCS-1, combining air temperature, relative humidity and day/night light detection in a single plug-and-play sensor.

The MBS-TH provides the Hydro-X controller with the environmental information it needs to manage compatible heating, cooling, humidification, dehumidification and other climate-control equipment.

Temperature and humidity are continuously measured and reported back to the Hydro-X, while the integrated photocell determines whether the growing area is in its light or dark period. The controller can then use these readings together with compatible TrolMaster Device Stations to automatically manage connected environmental equipment.

This product is supplied as a replacement or spare MBS-TH sensor. A 3-in-1 sensor is already included as standard with a new Hydro-X HCS-1 controller, making this unit ideal for replacing an existing sensor or keeping a spare available for an established installation.

Why choose the TrolMaster MBS-TH?

  • 3-in-1 environmental monitoring - combines temperature, relative humidity and day/night detection in one sensor.
  • Designed for Hydro-X - the standard environmental sensor used with the TrolMaster Hydro-X HCS-1 control system.
  • Continuous temperature monitoring - provides the controller with real-time air-temperature information for automated climate control.
  • Continuous humidity monitoring - allows compatible humidification and dehumidification equipment to respond to changing relative humidity.
  • Built-in photocell - automatically detects the presence of light so the controller can determine day and night operation.
  • Plug-and-play installation - connects to the Hydro-X sensor network using TrolMaster's RJ12 connection system.
  • 16ft RJ12 cable included - provides approximately 4.9m of cable for flexible sensor positioning.
  • RJ12 T-Splitter included - allows the sensor to form part of the Hydro-X daisy-chained sensor network.
  • Ideal replacement or spare - replace an existing MBS-TH without purchasing another controller.

Temperature & humidity monitoring

Environmental control depends on accurate information about conditions within the crop area. The MBS-TH continuously supplies the Hydro-X with air-temperature and relative-humidity readings, allowing the controller to compare actual conditions against the settings configured by the user.

Compatible TrolMaster control modules can then switch or regulate connected environmental equipment according to those readings. Depending on the equipment and Device Stations installed, a Hydro-X system can be configured to manage heating, cooling, air conditioning, ventilation, humidification and dehumidification.

The MBS-TH therefore acts as one of the primary environmental feedback sensors within a Hydro-X installation.

Built-in day/night photocell

In addition to temperature and humidity, the MBS-TH incorporates a photocell that allows the Hydro-X to identify whether lights are on or off.

The photocell detects the presence of light rather than measuring light intensity. It is therefore used for day/night detection and should not be confused with a PAR or PPFD sensor.

For growers requiring actual photosynthetic light measurement, TrolMaster offers the separate MBS-PAR Full Spectrum Quantum Sensor.

Environmental control with Hydro-X

The MBS-TH itself is a monitoring sensor rather than a switching device. Environmental equipment is controlled through compatible TrolMaster Device Stations connected to the Hydro-X controller.

The controller receives temperature and humidity information from the MBS-TH, compares those readings with the configured environmental settings and then sends the appropriate control commands to the connected Device Stations.

This modular approach allows the Hydro-X system to be configured around the environmental equipment already being used rather than requiring a fixed collection of devices.

Sensor positioning & installation

Position the MBS-TH where it can provide a representative measurement of conditions within the growing environment. Avoid locations directly affected by heaters, air-conditioning outlets, humidifiers or other equipment that could produce an unrepresentative local reading.

The sensor connects to the Hydro-X SENSORS port through the supplied RJ12 cable and T-Splitter. Additional compatible Hydro-X sensors can be daisy-chained using further splitters and RJ12 cabling.

Keep the MBS-TH dry and clean. TrolMaster specifically advises against spraying foreign substances onto the sensor or allowing water or condensation to collect on it, as contamination or moisture can cause premature sensor failure.

Hydro-X compatibility

The MBS-TH is specifically designed as the 3-in-1 environmental sensor for the original TrolMaster Hydro-X HCS-1.

It should not be confused with the MBS-PRO used by the Hydro-X Pro and Hydro-X Plus systems. The MBS-PRO is a different 4-in-1 sensor that additionally measures CO2 concentration.

TrolMaster MBS-TH FAQs

What does the TrolMaster MBS-TH measure?

The MBS-TH measures air temperature and relative humidity and uses a built-in photocell to determine whether the growing environment is in its day or night period.

Which TrolMaster controller is the MBS-TH designed for?

The MBS-TH is the 3-in-1 environmental sensor designed for the TrolMaster Hydro-X HCS-1.

Does a new Hydro-X HCS-1 already include an MBS-TH?

Yes. The Hydro-X HCS-1 is supplied with an MBS-TH sensor, so this separately supplied product is primarily intended as a replacement or spare.

Does the MBS-TH measure light intensity?

No. Its photocell detects whether light is present so the controller can determine day and night operation. It does not provide a PAR, PPFD or other light-intensity measurement.

Does the MBS-TH measure PPFD?

No. PPFD measurement requires a suitable quantum sensor such as the TrolMaster MBS-PAR.

Does the MBS-TH measure CO2?

No. The MBS-TH measures temperature, humidity and day/night light status. CO2 monitoring on a Hydro-X system requires a compatible separate CO2 sensor.

Can the MBS-TH control heating and cooling equipment?

The MBS-TH provides the environmental readings used by the Hydro-X. Actual equipment is controlled through compatible TrolMaster Device Stations connected to the controller.

Can it be used for humidity control?

Yes. The MBS-TH provides relative-humidity readings to the Hydro-X, which can then operate compatible humidification or dehumidification equipment through the appropriate control modules.

How does the MBS-TH connect to the Hydro-X?

It connects to the Hydro-X sensor network using an RJ12 cable and T-Splitter.

What cable is included?

TrolMaster supplies the MBS-TH with a 16ft RJ12 cable and an RJ12 T-Splitter.

Can other sensors be connected to the same Hydro-X sensor network?

Yes. Compatible sensors can be daisy-chained through the Hydro-X sensor connection using RJ12 cables and splitters.

Where should I position the MBS-TH?

Position it where it can measure representative environmental conditions. Avoid placing it immediately beside equipment or air outlets that could artificially influence temperature or humidity readings.

Can the MBS-TH get wet?

No. TrolMaster advises keeping the sensor dry and clean and specifically warns against spraying substances onto it or allowing water or condensation to contact the sensor.

Is the MBS-TH the same as the MBS-PRO?

No. The MBS-TH is a 3-in-1 temperature, humidity and day/night sensor for the Hydro-X HCS-1. The MBS-PRO is a different 4-in-1 sensor that also measures CO2 and is designed for TrolMaster's Hydro-X Pro and Hydro-X Plus systems.
