In order to measure air pollution dust sensors play an important role. They are often based on an optical system where light, scattered on dust particles is measured. I have 3 different sensors which should allow me to compare results:

Plantower PMS5003. I found 2 manuals for this sensor:
- PMS5003 data sheet
- PMS5003 air quality sensor experiment
The Shinyei PPD42NS
The Sharp GP2Y1010AU0F
- GP2Y1010AU0F data sheet
- GP2Y1010AU0F application note

The Plantower PMS5003 sensor

The pinout table for the PMS5003 is given below (the colors correspond to my cable and yours may well differ)
