The use of preferences and SPIFFS ensures that configuration data is stored persiste
Air quality module, measures parameters: CO2, PM2.5 (PM1.0, PM10), Temperature, Relative Humidity, pressure. It sends this data to the HiveMQ MQTT platform via WiFi using strings while displaying the results on an LCD screen every 4 seconds. The sent data is sent to the following website, where a demo is available for you to try.
