Ultimeter Weather Station


Current weather at my house.

peetbros.com

The weather station runs as a background process once per minute, logging the current time, temperature, wind direction and speed to a file.

Note that PBU2100.py provides a way to define the data you would like to have displayed as text. It is easy to log this to a text file or a CSV file.
