Non--dispersive infrared (NDIR) sensors are widely used to measure gas concentrations. However, there is currently no complete mathematical model for NDIR sensors available to speed-up the development process of new sensor alterations. This paper reports on an ongoing research to derive and verify accurate mathematical models for various components of NDIR sensors. In this paper, mathematical models for main components of an NDIR sensor are presented. They cover among others the thermal light source and the behavior of the thermopile detector. Finally, each mathematical model is verified by measurements.
