2. About the PMS5003 (PM2.5/10)
Digital and universal particle concentration sensor
Can be used to obtain the number of suspended particles in the air (aka can measure air quality)
Can provide data of concentration over time
Data collection specification:
Can collect particulate matter per 0.1L air,
Gets categorized into 0.3um, 0.5um, 1.0um, 2.5um, 5.0um and 10um size bins

3. How it Works
Scattering is produced by using laser scattering to radiate suspending particles in the air
The scattered light is then collected at a certain degree
Finally, data can be obtained of scattering light change with time
Equivalent particle diameter and the number of particles with different diameter per unit volume can be calculated by microprocessor based on the Mie theory on light scattering

4. Air Quality Index
Data measured from the particulate sensor can be compared with published AQI data by converting the concentrations given by the sensor to tabled values
The following table shows the AQI value range along with the sensor ranges. The PM concentrations are 24 hour ranges.
