      • Ok, cool. I’m new to air quality and I’ve been testing that unit. You have reviewed the PM2.5 and HCHO sensor readings from it but not TVOC. I took a variety of readings and found you can calculate the TVOC reading from the HCHO implying they are not separate sensors, is that normal? Here’s the formula which works on your screenshots also: TVOC = -0.00991 + 4.37716 * HCHO + 1.63941 * HCHO ^ 3

      • In my device they are two separate sensors but in another device that a friend has there is only one sensor for both pollutants. So your formula may actually be real. Thanks Paul.
