Overview | Air Quality Sensor | Adafruit Learning System

20211122· ( refers to particles that are microns or smaller in diameter.) This sensor uses laser scattering to radiate suspending particles in the air, then collects scattering light to obtain the curve of scattering light change with time. The microprocessor calculates equivalent particle diameter and the number of particles with different diameter per unit volume.


PMS5003 Sensor Accuracy? Sensors Arduino Forum

20211125· Using Arduino Sensors. cds333 November 25, 2021, 12:48am 1. So I have been experimenting with the Plantower PMS5003 sensor to measure air quality. But I have no way to know what the default values should be. As usual, everyone else who reviews one of these things only ever does so with a single unit, and therefore does not test repeatability.
