I love collecting and analyzing data. I also love building electronic gadgets. A year ago when I discovered the Arduino products, I immediately thought, "I'd like to collect environmental data." It was a windy day in Portland, OR, so I decided to capture wind data. I looked at some of the instructables for anemometers and found them quite useful, but needed to make some engineering changes.
First, I wanted the device to run self-contained, outdoors, for a week. Second, I wanted it to be able to record very small gusts of wind, several of the designs here required rather strong winds to get going. Lastly, I wanted to record the data.
