Solution
When start the operation, the sensor may become unstable
in sensitivity and the color of the odor sensor may not
change.

sensor sensitivity will become stable.

air is clean. It may be difficult to sense odor. When you blow
cigarette smoke to the sensor or slap a towel near it, if the
colors of the odor sensor and dust sensor have changed,
this means that the sensor is working properly.
If you switch the unit on when the room has a strong smell,
the sensitivity of the odor sensor may be deteriorated.

or whole day.
Sometimes, the sensor sensitivity does not match the room
