Calibration to measure CO2 by sensor mq 135 Sensors ...

+

May 06, 2021· To calibrate, we measure two known gases with the device… usually 20% O2, 0% CO2 for the first gas, and 16%O2 and 5% CO2 for the second. This gives us two points on a curve for each sensor. Then it’s just a matter of applying the offset, assuming the sensor response is linear…. Hope that helps a bit…. MQ135 is not a realiable sensor, it ...
