It updates every minute. We are getting good overnight voltage data for our CO2 sensor which will help us get *real* ppm values, which are currently based on a zero-point voltage and drop voltage that is clearly under-calculating co2 ppm values.
We haven’t gathered enough days of data to fully calibrate our sensor, but we’re very close! We also named our project, Swapna put together an awesome visualization, and we’ve worked on implementing the coin-operating aspect, which we’ll play-test in class. Our as-of-yet sparsely commented code is on github.
