Weather Station Components

Outdoor Components

The outdoor components (see
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 vane, 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.
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 "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.
Plenum-rated data cable
the master control unit (MCU), located indoors. Conduit (not included) is not required if the
cable is run indoors in a building plenum.
* Plenum-rated data cables are UL listed as having adequate fire resistance and low smoke-producing
characteristics for installations without conduit in ducts, plenums and other spaces used for environmental
(shared) air.
NOTE: Cable should not be installed on rooftop surfaces without protective conduit
(not included).
