---+ Dust Sensors
---++ Introduction

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:
      * [[http://www.aqmd.gov/docs/default-source/aq-spec/resources-page/plantower-pms5003-manual_v2-3.pdf][PMS5003 data sheet]]
      * [[https://www.rigacci.org/wiki/lib/exe/fetch.php/doc/appunti/hardware/raspberrypi/pms5003-and-pms7003-experiment.pdf][PMS5003 air quality sensor experiment]]
   * The *Shinyei !PPD42NS*
      * [[https://www.switchdoc.com/wp-content/uploads/2018/08/Grove_-_Dust_sensor.pdf][Shinyei PPD42NS product specification]]

      * Paper: [[https://jordifonollosa.files.wordpress.com/2015/01/dust_sensor.pdf][Test of Particle Sensor (PPD42NS, Shinyei)]]
   * The *Sharp !GP2Y1010AU0F*

---++ The Plantower PMS5003 sensor

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

| Pin number | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 |
| signification | nc | nc | reset (active low) | Tx (3.3V level) | Rx (3.3V level | set pin (3.3V or open: normal working status) | Gnd | Vcc: 5V |
| on ESP32 | | | D0: GPIO 26 | D1: GPIO 22 | D2: GPIO 21 | n.c. | Gnd | 5V |
| cable color | n.c. | n.c. | black | gray | white | violet (n.c.) | blue | green |
