Hi Jonathan, did you take a look at my project site pits.tgd-consulting.de ? I am using a PLANTOWER PMS7003 sensor to monitor particular matter (dust), a BME280 I2C-sensor modul to measure temperature and humidity. Optionally you can monitor volatile organic compounds (VOCs) simple and effective with an ADS1015 ADC and the Figaro TGS2600. All measurements for each sensor are shown separately in a graph on builtin webserver. TGD
