14. Range
The range for radio signal transmission between the outdoor sensor and the weather station is up to 50 m at optimal
conditions.
This value is the so-called “free field range”.
This perfect alignment (e.g. outdoor sensor and weather station on a smooth, level meadow without trees,
houses, etc.), however, is never present in practice.
Normally the weather station is set up in the house and the outdoor sensor under a roof protrusion, e.g.
below a car port.
Due to the different influences on radio transmission, no specific range can be guaranteed, unfortunately.
Usually, however, operation in a family home is possible without any problems.
If the weather station doesn’t receive any data from the outdoor sensor (despite new batteries), reduce
the distance between the outdoor sensor and weather station, change the installation site.
The range may be considerably reduced by:
• Walls, reinforced concrete ceilings
• Laminated/coated insulating glass panes
• Vehicles
• Trees, shrubbery, earth, rocks
• Proximity to metal & conductive objects (e.g. heater)
• Proximity to the human body
• Broadband interference, e.g. in residential areas (mobile phones, radio headphones, radio speakers, other radio
weather stations, baby monitoring systems, etc.)
• Proximity to electrical motors, transformers, mains adapters, computers
• Proximity to badly shielded or openly operated computers or other electrical devices
• Low outdoor temperatures (batteries and rechargeable batteries are sensitive to temperature!)
