Temperature Compensation of Novel NDIR CO2 Gas Sensor

We have designed novel optical cavity and simulated it for NDIR gas sensor application. Novel optical cavity enhanced the light focusing effects. In this research, we developed the temperature compensated NDIR CO 2 gas sensor for heat exchange system. The output characteristics of developed sensor module shows an exponentially decreasing property and all parameters are temperature dependent. The temperature compensated module has about plusmn 70 ppm error within 40degC temperature span.
