The particle data collection time is about 1.5 seconds when the AQM is just running, and it
will be collected every 1 minute after running for 30 minutes. When the product is
charging, the data will keep refreshing every 1.5 seconds.
Note: Temperature and humidity refresh data every 5 seconds.
**Refers to EPA standards,with PM2.5 as the main responsible pollutant.
(Bracket included)
Q: Why is the PM2.5 reading constantly changing?
A: As PM2.5 concentration in the environment is changing all the time not only
due to environmental factors like changes in airflow, humidity, wind direction
and etc. but also due to common pollutant sources like smoking, cooking;
exhaust emissions from vehicles, smoke from burning coal/chimneys/furnaces
and etc. All these may influence the PM2.5 concentrations and give dierences
in the readings.
Q: Why is the test result abnormal ?
A: ① Please check whether the air inlet or outlet is covered or liquid has entered.
② Gently shake the detector during detection to increase the interaction with
surrounding air.
③ The sensor may be not recovered, Please place the detector outdoors for
ventilation.
Q: Why data reading is unstable?
A: If the airflow in the current sampling space is in an unstable state, such as
strong wind, the concentration of particulate matter in the air will be unevenly
distributed, and will vary greatly with the surrounding airflow, resulting in large
dierences in measured values.
FAQ
Q: Why is the product data higher near the light source?
A: Our sensor uses the principle of light scattering, and the photosensitive
element is close to the air inlet. If a strong light source is used to illuminate the
position of the air inlet, it will interfere with the light signal and aect the data.
Therefore, it is necessary to avoid direct glare from the air inlet.
Q: AQI/ PM2.5 and other values, why the measured value is inconsistent
with the ocial announcement?
A: The AQI/PM2.5 shown on the display is a measurement of the space where
the device is located. The measured value published on the Internet or ocial
websites is the average value of several monitoring points, and each
measurement point will be dierent. At the same time, according to the
regulations of EPA and WHO, the AQI value is calculated based on the highest
value among the five pollutants in the atmosphere on that day. In the past ten
years, the local AQI in the United States has basically been calculated with the
value of PM2.5/PM10, and sometimes with the value of O
3.
