15. Range
The range for radio signal transmission between the outdoor sensor and the weather station
is up to 100 m under best conditions.
However, these range values refer to the so-called “free field range”.
This perfect alignment (e.g. weather station and outdoor sensor on a smooth, level
meadow without trees, houses, etc.), however, is never present in practice.
Usually, the weather station is put up in the house, and the outdoor sensor next to a
window.
Due to the different influences on radio transmission, no specific range can be
guaranteed for, unfortunately.
Usually, however, any operation in a family home is possible without any problems.
When 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
• Coated/metallised insulated glass, aluminium windows, etc.
• Vehicles
• Trees, shrubbery, earth, rocks
• Proximity to metal & conductive objects (e.g. heater)
• Proximity to the human body
• Broadband interferences, e.g. in residential areas (DECT telephones, mobiles, radio-
controlled headphones, radio-controlled speakers, other radio-controlled weather stations,
baby phones etc.)
• Proximity to electric motors, transformers, mains adapters
• Proximity to mains sockets, mains cables
• Proximity to badly shielded or openly operated computers or other electrical devices
