Hello. I have a CO2 sensor that hooks up to a relay board for atmospheric control. The sensor outputs a voltage linear to the concentration of CO2 present (.5v = 0ppm, 4.5v = 2000ppm. I'm wondering if there is a way to incorporate a display that will not display the linear voltage but the relative ppm concentration. I was thinking a simple meter display but again, I'm looking for the relative ppm. Thanks
