I had an idea... Once I get my solar panels in place, I'd like to wirelessly log the temperature, voltage, and position of each panel through each day of the year. I'd like to send this data to a PC for graphing purposes.
Is there anything out there that already does this cheaply? If not, do you guys think this is something that people would want? If so, how much do you think people might pay for something like this? $20, $50...?
Another project of mine is getting into the the business of selling various electronics kits for hobbyists to build on their own. So, I'm trying to test the level of interest in an idea like this one.
