Signal conditioning for NDIR sensor Application note

Non dispersive infrared (NDIR) is a quite old technology as the first research was carried out in 1930’s in the USA by the department of defense. The commercialization of NDIR started in the 50’s without never reaching big volumes mainly due to its size and output drift over the time. This technology finally reached its full potential in 2010 when new technology of NDIR appeared allowing ...
