What is an NDIR Sensor? - Sensor Technology | Sensors ...

· Sensors continued to get smaller, when in 1993, an engineering breakthrough occurred; SenseAir AB patented a design for CO2 sensors with a small-footprint. As a result, the size problem of the sensors was solved by using folded optics and metalized molded plastic. This was able to reflect the light through a curved shape ('waveguide') that was lengthier than the footprint of the sensor module ...
