TrolMaster MBS-WS Weather Station Sensor for Green-X Controller - RS485 - IP54 - 12 ft Cable

Outdoor Weather Data for Your Controller - 12 ft Cable Included

Indoor climate decisions work better when you know what the weather is doing outside. The TrolMaster MBS-WS combines temperature, humidity, wind speed and rainfall sensing in one compact unit and sends the readings over RS485 digital communication. It is built for use with TrolMaster control systems, and it is rated IP54 for outdoor mounting.

Sold individually, this unit suits a single site or greenhouse that needs one outdoor reference point. Growers running several sites will need one sensor per location.

Key Features & Benefits

• Four measurements in one unit — temperature, humidity, wind speed and rainfall from a single mounting point.
• RS485 digital communication — stable data transmission to the controller.
• Three wind spoons — wind speed readings from 0-15 m/s.
• IP54 rating — made for outdoor exposure.
• Mounting hardware included — bracket, horizontal tool and 12 ft cable come in the box.

Who Should Use TrolMaster MBS-WS

Greenhouse operators, indoor growers who track outdoor conditions, and anyone using a Green-X controller who wants weather-based control inputs.
