The Bathgate Weather Station has a total of 29 sensors monitoring the local environment 24 hours a day. The sensors
are associated with four Davis units - the primary weather station is a Davis Vantage Pro2 (VP2), with a secondary
Davis Vantage Vue (VUE) weather station. In addition, a Davis Airlink (AL) unit measures local Air Quality and a Davis
WeatherLink Live (WLL) unit ensures weather data is captured and stored, as well as providing three further indoor
The specificatons of each of the weather station sensors is provided in the adjacent tables.
Augmenting the data directly collected via the station sensors many more additional weather parameters can be calculated,
such as Dewpoint, Wind Chill, Hours of Sunshine etc. This enables an extremely detailed view of the current weather
conditions in Bathgate to be displayed on the website.
Davis Vantage Pro2 (VP2):
The primary weather station of Bathgate Weather. This system provides the key weather information from three transmitting
units. The Temperature, Humidity, Rainfall, Solar Radiation and UV Index sensors are located within the Intregrated Sensor
Suite or ISS. The ISS is located on the rear garden fence, 1.5 metres above the ground. Wind information is provided by
a separate transmitter, the Anemometer is located 2 metres above the roof line which is 10 metres above the ground. The
final transmitter provides the Ground and Decking Temperatures, the Soil Temperature and Moisture (both 10cm below the
ground surface) and finally the Leaf Wetness reading.
The Barometric Pressure, Indoor Temperature and Humidity information is supplied by the indoor console unit which receives
all of the data transmitted from the outdoor sensors.
Davis Vantage Vue (VUE):
This secondary weather station acts as a backup to the primary VP2 station. Situated in the same location as the VP2 it
provides Temperature, Humidity, Rainfall, and Wind data. As the VUE wind sensors are located in the same unit the
values obtained are much lower than the VP2 as they are in a more sheltered location. The Vue wind sensors are 2 metres
above the ground but only 10 metres from buildings which block the prevailing South-Westerly wind. The rain gauge also
appears to read approximately 5% to 10% more rainfall than the VP2.
As with the VP2 the Barometric Pressure, Indoor Temperature and Humidity information is supplied by the indoor console
Davis Airlink (AL):
The Airlink unit is located at the front of the house within a sheltered porch area. The main function of this unit is to
report on the local Air Quality - however it also contains additional Temperature and Humidity sensors. The unit records the
levels of Particulate Matter (PM) detected in the air at three different sizes - 1 µg/m3, 2.5 µg/m3
and 10 µg/m3. The current Air Quality Index is calculated from the levels of 2.5 particules and shown on a scale
of 1 to 10.
Due to the sheltered location of the Airlink unit the Temperature readings can vary from that recorded by the VP2 and Vue units
- this is especially noticable during settled weather.
Davis WeatherLink Live (WLL):
This unit is primarily used to receive weather data directly from all of the other units and send this information to
Davis WeatherLink Cloud Storage. It offers three additional indoor sensors, Barometric Pressure, Temperature and Humidity.
