Conclusion. Non-dispersive infrared (NDIR) is a physical sensing technique that provides a number of advantages over catalytic gas sensing method. The main feature of this technique is that fixed narrow-band filters are utilized with separate IR detectors to detect a few gas absorption lines across a restricted wavelength range.
VOC Sensor p-type Metal Oxide This sensor is a broadband total VOC detector. When the cost of a PID is not justifiable, this sensor will detect VOCs with 10-50 ppb limit of detection, depending on the VOC. Unlike common n-type sensors, this metal oxide sensor has a large dynamic range, repeatable response, low humidity response and resistance increases in the presence of most VOCs. The change ...

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.
Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means it's bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific experiments, air quality and ventilation studies, and more. Compared to the illustrious SCD-30, this sensor uses a different measurement technique, which ...
