More Quantified

Or, the importance of error bars / confidence levels…

Today I received the Airthings Wave to monitor radon (we are in the western US!) – it is bluetooth to my phone at the moment, but I’ll have to see if I can actually log the data more permanently (maybe a raspberry pi bluetooth? WAHOO!). At any rate, it says we have a radon level of <0.3 (or 0.1 pCi/L) with 32% humidity and a temperature of 71F. Our Ambient weather station (about .75 m away) says 69.1F and 28% humidity.. The usual curse of making more than one measurement (means you don’t know which is correct!). At any rate, the radon sensor is going down the sub-stair enclosed area (aka beer basement) and we’ll see how that goes. I’ll have to see if I can get a bluetooth connection to a raspberry pi and do some real data logging.

In that vein, I’ve gotten munin going and have five of the local data loggers (sohpi itself, the picam, the shake, the boom, and the ads-b receiver) all reporting state of health data.

Data! the best way to counter anti-fact politicians..

    1. It is rock under the house – I’ve heard stories about all the blasting done to put the houses in on our cul-de-sac back in the early 1990’s.
