Weather Station Components
Outdoor Components
The outdoor components (see Standard Outdoor Components, on page 12) of a standard
WeatherBug Weather Station are:
• Sensor Shelter (with remote Temperature/Relative Humidity (TRH) Sensor mounted
inside)
• Wind Sensor
• Rain Gauge
• Data Cable
The Weather Station's sensor suite uses accurate and rugged sensors. The wind speed and
direction sensor is an R.M. Young wind sensor, widely acknowledged to be one of the top
Wind Sensors available. The Rain Gauge is a standard tipping bucket that measures .01
inches of rain per tip.
The remote Temperature/Relative Humidity (TRH) Sensor is a metal box about the size of a
deck of cards that is mounted inside the Sensor Shelter. The circuit board within the TRH
serves as an analog-to-digital (A-D) converter. Digital conversion provides a high degree of
accuracy and flexibility for distributing your weather station data.
The Sensor Shelter (often referred to as a convection-aspirated shelter) serves two primary
purposes:
• It shields the remote TRH sensor from direct sunlight, which could yield inaccurate
readings (the design minimizes heat build-up by enabling natural air currents to flow
through it, resulting in "true" air temperature readings).
• Second, it protects the remote TRH sensor from rain, ice and snow, which could
also produce inaccurate readings as well as cause damage to the relative humidity
sensor.
The Data Cable transports data from the weather station's outdoor components to the
BlueBugBox (BBB), located indoors. The Data Cable is UV-rated and can be run along the
weather station mast without conduit; however, conduit should be used to protect the cable
when running it over the length of roof and into the building. If your building codes require
different ratings of cable, please contact WeatherBug Weather Station Technical Support.
NOTE: Cable should not be run across rooftop surfaces without protective conduit
(not included).
