Signal conditioning for NDIR sensor - Application note

NDIR sensor. Bandwidth. The pulsed light of the IR source of the NDIR sensor works generally at a very low frequency (few Hz). It is important to limit the bandwidth of the application as much as possible in order to limit the noise. A first order low pass filter is realized thanks to the RC network. with a -3 dB cut-off frequency ...
