How does an NDIR CO2 Sensor Work? |

+

Because the IR spectrum of CO2 is unique, matching the light source wavelength serves as a signature or "fingerprint" to identify the CO2 molecule. As the IR light passes through the length of the tube, the CO2 gas molecules absorb the specific band of IR light while letting other wavelengths of light pass through. At the detector end, the remaining light hits an optical filter that absorbs ...

The CO2 concentration is calculated from the measured resistance and the temperature/relative humidity correction. It may be written as: CO2 = 410*ppm*(Rs/f_RH_T / Rs410/f_RH_T_410)^b. Where the exponent b is equal to according to Mad Frog. And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is ...

15/08/2021· When the detector sees IR signal, it will pull the output low, turning on the LED since the LED is red its much easier for us to see than IR! We will use 4xAA batteries (I use NiMH) so that the voltage powering the sensor is about 4V. 2 batteries (3V) may be too little. 3 Batteries should be fine if you have a tripleAA holder. You can also get 5V from a microcontroller like an Arduino ...
