CO2 Monitoring with K30 Sensor Arduino Project Hub

I tried a number of analog CO2 sensors for that project, but I ran into calibration issues until I got a K30 CO2 module. This is a NDIR, digital, autocalibrating sensor, so it''s pretty easy to use. I am now starting a new open source project, this time using Arduino. I uploaded a I2C library for this sensor on Github: K30_CO2_I2C_Arduino. This photo shows K30 connected to Arduino. CO2 ...

NDIR Principle | Cambustion

NonDispersive InfraRed (NDIR) detectors are the industry standard method of measuring the concentration of carbon oxides (CO CO2). Each constituent gas in a sample will absorb some infra red at a particular frequency. By shining an infrared beam through a sample cell (containing CO or CO2), and measuring the amount of infrared absorbed by the sample at the necessary wavelength, a NDIR ...
