Fluorescent cap daily storage
Put it in a protective cover with a moist sponge when not in use,
so that the sensor stays wet for a long time.
If the head of the sensor's fluorescent cap is dry for a long time,
it will cause drift of the measurement result, so it needs to be
immersed in water for 48 hours before continuing to work.
