• Do not throw the battery into the fire to prevent the battery from exploding. Damaged batteries may also explode.
• The average time that PM2.5 Dust Sensor is without any failures is 3 years. If the concentration is more than 300ug/m3 for
more than 50% of a year, or the concentration exceeds 500ug/m3 for more than 20% of a year, the consistency of the sensor
will decrease. The data may be high because of the internal dust accumulation.
All the above suggestions apply equally to your device, batteries, and accessories.
