MH-Z19B (CO2-sensor) Dit is de goedkoopste optische CO2-sensor. Wijkt makkelijk 50 PPM af van de realiteit maar dat is nog steeds goed genoeg om te bepalen wanneer de ramen open moeten. Er zijn goedkope TVOC-sensoren met "eCO2"-uitlezing, maar dat is wel te slecht. De sensor calibreert zichzelf automatisch in cycli van 24 uur.
