Correlating Data

After analyzing any measurement values I always ask myself the same question, is this data wrong or not?. To check if my temperature measurements were good enough I gathered in all the thermometers in my home and placed next to the Arduino+LM35. Then I confirmed that the LM35 was doing a good job, but that wasn´t enough, I needed to know if the measurement of the LM35 could be at least a naive model of the whole room temperature. To do so I started working with PyEphem and probed that the temperature data was correlated with the sun altitude.

Plotting Data

Data is almost useless without a proper view. After storing the temperature data I need a way to plot this information so I can infer something. Let´s face the 'artistic' stage of the project.

Debian Etch + Temperature Logging

Time to store the data. Being able to sense the temperature it's just the first step, storing and plotting the resulting data is the power, muhahaha, muhahaha
