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.

Some of the configurations supplied to our customers have included:

 ►    Wind speed, wind direction, relative humidity, air temperature, rainfall,

         water pH, water dissolved oxygen, water level.
 ►    Wind speed, wind direction, air temperature, NOx, CO, H2S
 ►    Wind speed, wind direction, solar radiation, UVA, UVB, net radiation,

         relative humidity, air temperature, ground temperature, panel temperature, leaf wetness, rainfall.
