thmjprbang Its going to be indirectly estimating CO2 with a sensor like the CCS811. That is likely why they say to calibrate it, a true CO2 sensor is pre-calibrated. I will order one and find out. I received it: has one sensor looks similar to SGP30, but SGP30 only measures VOC and eCO2. So not sure how they measure formaldehyde.
