16. Range

Under optimum conditions, the transmission range of the radio signals between the temperature/air sensor and the
weather station is up to 100m, the transmission range between the rain sensor and the wind sensor to the weather
station up to 30m.
However, the range values refer to the so-called "free field range".
This ideal arrangement (e.g. weather station and outdoor sensor on a plain, even meadow without
trees, houses etc.) never exists in practice.
Normally, the weather station is installed inside the house, the temperature/air humidity sensor next to
a window, and the rain and/or wind sensor on a carport, for example.
Due to the different influences on radio transmission, it is not possible to guarantee a specific range.
However, trouble-free operation is usually possible in a detached house.
If the weather station does not receive any data from the outdoor sensors (despite new batteries),
reduce the distance between the outdoor sensors and the weather station, change the installation site.
The range can sometimes be considerably reduced by:
• walls, reinforced concrete ceilings
• coated/vapour-deposited insulating glass panes
• vehicles
• trees, brushes, earth, rocks
• proximity to metallic & conductive objects (e.g. radiators)
• 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, power pack units, computers
• proximity to badly shielded or openly operated computers or other electric/electronic devices
