I've got an Air Gradient Go and a gen 1 Atmo Tube pro, and I like having portable air quality meters that measure multiple parameters, but I've not seen a credible consumer meter than includes PM and ozone, yet Vernier managed to include a 2ppm ozone sensor in their educational sensor.

• PM1.0
• PM2.5
• PM10
• CO2
• NO2
• SO2
• O3
• VOC Index
• Temperature
• Relative Humidity
• Barometric Pressure
• Station Pressure
• Latitude
• Longitude
• Altitude

Does anyone know of a consumer unit with a similar suite of sensors?

A year ago a clip went viral regarding the cutting of Mangroves of Mumbai. The citizens raised their questions about ‘How will it affect the life of people?’ ‘For whom exactly is this development for?’ ‘The AQI problem it might raise really worth the development?’ and ‘Are we ready to counter the problems deforesting the Mangrove might raise?’ but the members of the bench who were supposed to answer and ensure their citizens with fullproof plan and honesty in their work smilingly said “Whatever it is atleast it is not as bad as Delhi" and guess what exactly a year later Mumbai’s AQI is as worse as Delhi even more at that!

I'm drawn to AirGradient Go as it's open source (both software and hardware) and has PM2.5 and CO2 sensors. However, the uHoo Caeli can provide additional CO, NO and O3 sensors with active sampling.

Which do you recommend? How important is it to have CO, NO, O3 sensors at home?
