---+ The Plantower PMS5003

The PMS5003 uses a serial interface with a baud rate of 9600 Baud.

Here are the pin descriptions from the data sheet:

The pinout table for the PMS5003 connection is given below (the colors correspond to my cable and yours may well differ). The Plantower sensor may be connected to a PC using a USB to serial interface or to the ESP32 with the pin connections in the table.

Readout programs can be downloaded from my github repository https://github.com/uraich/dust-sensors/tree/main/plantower
