I've always been interested in monitoring my local weather, and noticed the difference between what weather.com and accuweather.com think my local weather is, and what I see out the window. I also wanted better control over my heating and A/C system. As a computer and electronics nut, I've been playing with the Arduino Microcontroller, and decided to to meld my interests. So here goes the documentation on my home built solar powered weather station (always being modified, and expanded) with HVAC Control.
UPDATE: Wind Speed Monitoring
The first step was obtaining a Arduino board. We purchased ours from hacktronics.com. After working through the tutorials on their site, I felt confident that I understood the simple scripting and connection concepts, and moved forward.
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. - http://arduino.cc/
The Arduino requires 5v to run, and we supply this with our Pico Solar PV / Lithium battery pack.
