Titus's Weather Page

Welcome to my weather page! Here you can see how windy and cold it has been. The weather monitoring equipment is homemade, and located on a pole above my house in Avondale (a suburb of Christchurch in New Zealand).

Plots are updated hourly; refresh this page to make sure you have the latest information.

Temperature and pressure are measured via analogue sensors connected to 8-bit analogue to digital converters. These are read via the parallel port of my computer every 3 seconds, and the average value logged every ten minutes.

The anemometer contains an infrared LED and transducer arranged so that a signal is sent down the wire each revolution. The signals are counted with an 8-bit counting chip, with the sum communicated to the computer every 3 seconds also via the parallel port. The "max gust" plot corresponds to the maximum 3 second speed recorded in a 10 minute period, while the "average" speed is the average of all the 3 second speeds recorded in the same 10 minute period.

On the software side the computer runs Windows XP. Data collection is completed by a python script, data are stored in a MySQL database, and plots are produced using GNUPlot.
