NDIR CO2 click is an advanced integrated CO2 gas sensor system, which is able to measure an absolute CO2 concentration, by utilizing the CDM7160 integrated sensor. This sensor is based on nondispersive infrared sensing principle (NDIR), with two detection elements: one is used for detecting the wavelength of the IR light spectrum, affected by the CO2 gas, while the other detects the …
· Its normal for the first CO2 reading to be 0, simply ignore the first reading when logging data. The sensor has a lot going on, there's temperature and humidity reading thanks to an SHT31 sensor on board. These values are used internally to normalize the NDIR CO2 readings as well. You can only get data every 2 seconds, which is pretty fast for this kind of sensor! If you want to slow down the ...

For CO 2 in synthetic air, gas response ranges from ∼ % at 100 ppm CO2 concentration to ∼ %. Hence, in this work, NDIR CO 2 gas responses in general, ranges from ∼2% to ∼40 % for CO 2 gas concentration from 100 ppm to 5000 ppm respectively.
This % (100ppm) change is outside the 100-300ppm range of accuracy of a typical 100% CO2 sensor. The sensor would probably not record any change. However, the accuracy of a 10,000ppm NDIR sensor is around 50ppm (%). This means that while you might not see an exact 100ppm change, you'd see a rise between 50ppm and 150ppm CO2.
