Candidato possibile: MQ135 Cosa vede:

Contro: Il sensore ha una sensibilità elevata e tempi di risposta rapidi, ma impiega pochi minuti per dare letture accurate perché il sensore deve riscaldarsi. I valori di misura del sensore vengono emessi come valori analogici, che possono essere facilmente valutati con un microcontrollore.

The BME688 reacts to most volatile compounds as well as many other gases polluting indoor air (exceptions are very few gases which are chemically pretty inert, e.g. N2 and CO2).In contrast to sensors selective for one specific component, the BME688 is capable of measuring the sum of VOCs/contaminants in the surrounding air.

CCS811 = co2 sensor HDC1080 = temperature and humidity sensor BMP280 = temperature and pressure sensor

C'è anche il BME680 che probabilmente è più economico del BME688

MQ135 forse il più attinente? (https://blog.robberg.net/mq-135-arduino/)
