· Most serious CO2 sensors are based on the NDIR (non-dispersive infrared) technology, consisting in measuring the number of CO2 molecules between a particular infrared light source and a detector. At the factory, the sensor manufacturer must perform a full sensor calibration with different CO2 concentrations to ensure a correspondence between the detector measures and the actual levels of CO2. The advantage of the NDIR technology is that the sensor …
sensor module and Room Controller. ESD Protection The CO 2 sensor module is an electronic device sensitive to Electrostatic Discharges. Always ensure you are properly connected to GND before handling the Room Controller and CO 2 sensor module. Use high caution when handling the CO 2 sensor module and avoid any contact with grey housing on CO 2 sensor module. Never
These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a 'waveguide') that was longer than the footprint of the sensor module. The highly reflective coating ensured that the CO2 molecules inside the gas sample chamber would absorb the same amount of light as traditional straight-path design.

The most accurate method of CO2 sensor calibration is to expose it to a known gas (typically 100% nitrogen) in order to duplicate the conditions under which the sensor was originally calibrated at the factory. ISO certification is available on our high-end sensors to verify this process for medical, research or scientific purposes. Nitrogen calibration is also required if CO2 levels between 0-400 ppm will be …
