| Ottery St Mary Weather Station |
![]() The Station is based on the Davis Weather Monitor II Console and instruments. These are located on the Antenna Mast in the Garden, in the best available sensor locations available at the site. The Console is then routed through a WeatherLink II Datalogger, and into an Intel Core 2 Quad Q8200, Ubuntu Linux based VMware Server. The Virtualised Weather Server is running Apache2, PHP5 and mysql5, as well as Weather-Display and WeatherDisplayLive. The station is backed up with UPS and battery backup for the Console. The Datalogger also has memory for 30 days of weather data in the event of software failure / hardware outage. Weather Data is backed up externally to a Flash Drive in case of Server crash.
Supplementary Sensors based on 1-wire technology is used for Soil Temp's, Solar Intensity, Leaf Wetness and Lightning. These are logged with the WD software and displayed. This is an Experimental setup, to add functionality to the station in the near future, when they have been fully tested and calibrated to known standards. The Whole Weather Station consumes 64 watts of electricity over an hour, and has been designed to eventually be run from sustainable energy. The station was installed in March 2006, and data is available via this website, fed from the local sensors and METAR data from EGTE (Exeter Airport) which is approx. 4 miles away from this location.
The Accuracy of this software is being compared with the actual weather, and will be refined over 2009. More information on the Accuracy work is published on the site.

Long term Trending of weather data has started now that an archive of more than 12 months has been recorded. This archive is kept in a mysql database, with a record being committed every 10 mins. This data is used for the 24 Hour graphs seen on the site, along with further data extracts that are in the process of being written. The Custom Graph facility provides the on-line lookup of any of the recorded weather data since the start of the station in April 2006. 
Other software used, such as the dynamic graphing code using jpgraph was written by the author, which is available on request.
