PDS Automatic Weather
Stations
A typical Automatic
Weather Station installation

Housed in a weatherproof enclosure (IP68), the AWS will record and
log data from the various sensors while mounted on a two meter mast,
a ten meter mast, or a custom mast/mounting.
The AWS is commonly powered from an rechargeable battery, which is
intern trickle-charged by a solar panel when located at remote
sites. As the power requirements of a station change due to
telemetry requirements and sensor power, the solar panel is sized to
suit the power demand of the particular configuration of the
station. Additionally, the AWS may be mains powered, if a mains
electrical supply is available or if solar power and mains is not
available then wind generation may be used.

The configuration of an AWS may vary due to the purpose of the
system but typically consists of:
A weather-proof enclosure containing the data logger, rechargeable
battery and telemetry (optional);
► Meteorological sensors;
► Solar panel;
► Mast;
Depending upon the purpose of the station as well as location
details, the base AWS sensor configuration is but not limited to:
► Wind speed and direction (cup and vane
or ultrasonic);
► Air Temperature;
► Relative Humidity;
► Global Radiation;
► Raingauge;
The Relative Humidity and/or Air Temperature sensor(s) are mounted
in a solar radiation shield which protects the sensor(s) from direct
heat from the sun and radiated heat reflected off the ground
surface.

► turbidity
► dissolved oxygen
► level (flow)
Air Quality
► NO2
► SO2
► O3
► CO2
► THC
► Particulates (dust)
