On the other hand, LED is another option for an infrared source. LEDs are able to reduce the size and power consumption of whole sensor, but infrared output is rather small and wavelength range is limited. So two LEDs are required when it is used for dualwavelength method NDIR sensors.
A NDIR gas sensor calculates the gas concentration by using the property that gas molecules (, CO 2) absorb infrared rays. Therefore, a NDIR gas sensor is equipped with an infrared light emitter that emits infrared light and an infrared sensor that detects infrared light, and the performance of NDIR gas sensor varies depending on the type of the light emitter and the infrared sensor that is installed.
