Weather Station Accuracy Comparison Table: Accuracy,
Resolution, Range, Update Rate
©2008 AmbientWeather.com All Rights Reserved
1. Accuracy, Resolution, Range, Update Rate
Accuracy is defined as is the ability of a
measurement to match the actual value of the quantity being measured.
Resolution
is defined as the number of significant
digits (decimal places) to which a value is being reliably measured.
Range
is defined as the amount or extent a
value can be measured. Weather

Wireless Range
All
wireless transmission ranges listed in the following table are line of site,
unless otherwise stated. Standard construction walls can reduce the
transmission distance by as much as 50%.
Metal
enclosures (trailers), aluminum siding, reflective insulation materials, water
(rain), reflective window treatments, and radio interference can greatly degrade
the wireless transmission signal.
