Example: read the humidity from a BME280 and send it once per minute.

Needs a BME280 MicroPython driver (not bundled) — e.g. robert-hh/BME280:
    mpremote mip install github:robert-hh/BME280
Different drivers expose slightly different APIs; adjust the read line below to
match the driver you install.
