In this article, we will explore how NDIR gas sensors eliminate false alarms and why they are the future of gas detection.
A non-dispersive infrared gas sensor (or NDIR gas sensor) is a simple optical gas sensor commonly used as a gas detector.
Most NDIR gas sensors use broadband light sources, gas chambers with highly reflective walls, optical filters, detectors, and electronics for signal processing.
NDIR gas sensors can detect a decrease in transmitted infrared light proportional to the gas concentration. The transmittance, the ratio of transmitted radiation energy to incident energy, depends on the target gas concentration.
Non-dispersive infrared (NDIR) gas sensors are used to measure the gas concentration in the surrounding atmosphere.
