## Long description

The GreenBlue GB540N is a wireless weather station designed for continuous indoor and outdoor monitoring of temperature and humidity. The system consists of a main display unit for indoor placement and an external wireless sensor that transmits environmental data to the display. The device provides separate readings for indoor and outdoor temperature and relative humidity, enabling users to track microclimate conditions in living spaces, offices or small greenhouses.
Advantages
The GreenBlue GB540N offers wireless data transmission between the external sensor and the indoor display, allowing flexible sensor placement without running cables. The clear display shows separate indoor and outdoor values for temperature and humidity, simplifying comparison of conditions. Intended for everyday use, the unit supports quick detection of temperature and humidity changes to aid adjustments to heating, ventilation or humidification. The compact design and user-friendly operation make it suitable for domestic and light commercial environments.
Suitable for
 Monitoring indoor climate in living rooms, bedrooms and offices
 Tracking outdoor or balcony temperature and humidity
 Maintaining conditions in small greenhouses or plant rooms
 Checking ambient conditions near heating or humidifying equipment
Key specifications
 Measurement parameters: air temperature (indoor and outdoor), relative humidity (indoor and outdoor)
 Sensor type: external wireless environmental sensor for outdoor placement
 Display: dedicated indoor display showing separate indoor/outdoor readings
 Transmission: wireless communication between external sensor and display
 Power: battery-powered units for both display and external sensor (batteries not specified here)
 Operating locations: indoor placement for main unit, outdoor-suitable placement for external sensor
How to use
Install batteries in the main display unit and in the external sensor according to the manufacturer’s instructions, then place the display in a stable indoor location and mount or position the external sensor outdoors in a sheltered spot away from direct sun and heavy rain. Allow a short period for the units to synchronize; the display will begin receiving temperature and humidity readings from the external sensor automatically. Use the display to view current indoor and outdoor values and observe changes over time. Periodically check battery condition and replace batteries when display or transmission performance degrades.
Usage recommendations
Place the external sensor in a shaded, ventilated location and avoid direct exposure to precipitation to ensure accurate outdoor readings. For indoor accuracy, install the main display away from heating sources, direct sunlight and steam-producing appliances. Replace batteries before expected low-temperature periods to maintain reliable wireless transmission and continuous monitoring.
