Tips: What should be noted during use and storage this air quality sensor?

Avoid installing the air quality sensor in areas with high thermal conductivity or locations that create a direct temperature difference from the measurement zone, as this may lead to inaccurate readings.
Do not fully encapsulate with resin materials or immerse it in an oxygen-free environment; otherwise, its performance may be damaged.
Do not operate in environments containing corrosive gases for extended periods, as such gases can deteriorate the sensor.
When powered on for the first time, the portable air quality sensor requires a warm-up time of more than 3 minutes.
Do not use this module in systems involving personal safety.
If the air quality sensor needs to be placed in a confined space, ensure that the area is well-ventilated.
