/*
  Particulate Matter Sensor firmware (ESP32 version)

  Written by Jonathan Oxer for www.superhouse.tv
   https://github.com/superhouse/PM25SensorESP32

  refactored by Willem Oldemans

  Read from a Plantower PMS7003 particulate matter sensor and a BME680
  environmental sensosr using an ESP32, and report the values to an MQTT
  broker and show them on a 240x240 LCD, with a mode button to change
  between display modes.

  External dependencies. Install using the Arduino library manager:
     "Adafruit GFX Library" by Adafruit
     TFT_eSPI.h
     Adafruit_NeoPixel.h
     Adafruit_Sensor.h
     Adafruit_BME680.h
     AdaFruit_SCD30.h
     "PubSubClient" by Nick O'Leary
     RunningMedian

  Bundled dependencies. No need to install separately:
     "PMS Library" by Mariusz Kacki, forked by SwapBap
