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 Station Accuracy Comparison Table: Accuracy, Resolution, Range,

(1)   whichever is greater

(2)   Corrected to sea-level pressure. Raw pressure and altitude range unknown

2.     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.
