INTRODUCTION
- Air Pressure (WS2635 / Barometer):
A barometric pressure sensor is located within the receiver unit itself. The
barometer monitors the atmospheric pressure, which is the amount of downward
force exerted by the weight of the air, and is measured in inches of mercury (Hg).
Air pressure fluctuations are an important factor in predicting changes in the
weather.
- Wind speed and direction gauge (WDS500 / Anemometer):
The wind speed and direction is measured by the anemometer sensor, and this
data is wirelessly transmitted to the receiver. The direction of the wind is
displayed on a digital compass and the speed is given in km/h or mph.
- Rain level gauge (RD700 / Pluviometer):
The rainfall is measured and recorded by the rain gauge; it can be displayed in
millimeters or in inches by the receiver. The rain gauge gathers precipitation until
its inner "tipping bucket" mechanism is full, then the bucket tips and the liquid is
released. Every minute, the rain gauge calculates the number of times the bucket
has tipped; then transmits this data to the receiver. The total accumulated rainfall
(for the last hour, the present day, or for the previous day) may be displayed.
