    co2_sensor: wait for acclimatization after startup · dcba0a6a
    Käppler authored
    The SCD30 sensor has a response time of 20 s to reach
    67 % of its final reading. The first measurement
    can thus be unreliable, if the environment changed
    shortly prior to startup. Set measurement interval to the
    shortest possible value (2 s) and wait then, until the
    measurements have stabilized. Show a blue led effect in
    the meanwhile.
