Indoor Air Quality in Classrooms and COVID19 - CO2 Meter

According to ASHRAE, the recommended CO2 level in buildings should be no more than 700 parts per million (ppm) above outdoor air. Since outdoor air is approximately 400ppm, indoor CO2 levels should be no more than 1,100 ppm. Note that this guideline is not designed to limit the amount of CO2, but rather to indicate that a proper level of clean air (15-20 CFM/person) is being distributed in indoor spaces like …

How does an NDIR CO2 Sensor Work? |

Small NDIR CO2 sensor breakthrough. An engineering breakthrough occurred in 1993 when SenseAir AB patented a design for small-footprint CO2 sensors. 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 …
