How NDIR CO2 Sensors Work. NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. An NDIR sensor comprises an infrared source, a light tube, a bandpass filter, and a detector. The target gas is determined through the filter wavelength choice.
The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor that will tell you the CO2 PPM (partspermillion) composition of ambient air. Unlike the SGP30, this sensor isn''t approximating it from VOC gas concentration it really is measuring the CO2 concentration !

Prana Air CO 2 sensor is based on NDIR (Non Dispersive Infrared radiation) technology. This technique is widely used to detect carbon based gases that are present in air. The absorption wavelength of carbon dioxide in this technology is um. The infrared radiation is passed through the carbon dioxide gas when it hits the sensor surface.
Many sensors have to be used simultaneously for multipoint carbon dioxide (CO(2)) observation. All the sensors should be calibrated in advance, but this is a timeconsuming process. To seek a simplified calibration method, we used four commercial CO(2) sensor models and characterized their output te …
