---+ 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.
---++ 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 |
