Arduino apartment part 2

A year after my first temperature sensor experiment, I’m still chilly. I moved to Southern California, but the new landlord hasn’t managed to turn on the heater in the apartment.

Sounds like the perfect time to set the Arduino in the kitchen overnight and plot my apartment’s temperatures against the local Wunderground hourly outdoor readings.

These best-fit curves appear to follow a similar shape to last year’s plots, but I started earlier in the evening this time. My sleep pattern changed quite a bit from last year, and I took the 2014 readings on a Sunday night between 9:51 p.m. and 6:15 a.m. as a result.

Although the curves are similar, moving a place with no winter appears to have affected the minimum temperature. And is that bump just before 6:00 a.m. my coffee heating up?
