What this is
A small sensor node (Adafruit CLUE) sits ~1 m from the geophone, logging pressure, tilt, temperature and humidity once a second. It exists to explain slow station noise: pressure and tilt are the leading suspects for the sub-Hz ground undulation the seismometer sees.
Temperature reads the board’s own self-heat, not room air, so only its changes are meaningful. Values mirror here about once a minute; the page refreshes every 15 s.
