A Miniaturised, Fully Integrated NDIR CO2 Sensor On-Chip

In this paper, we present a fully integrated Non-dispersive Infrared (NDIR) CO2 sensor implemented on a silicon chip. The sensor is based on an integrating cylinder with access waveguides. A mid-IR LED is used as the optical source, and two mid-IR photodiodes are used as detectors. The fully integrated sensor is formed by wafer bonding of two silicon substrates.

Nondispersive infrared sensor - Wikipedia

NDIR Gas Measurement Principle. To measure the gas concentration with precision, you need two thermopile sensors and an infrared light source. One sensor serves as reference to monitor the variation of IR source output due to source aging, power variations, etc.. The other sensor is equipped with a gas-specific narrow band optical filter.

How does an NDIR CO2 Sensor Work? |

In addition to a smaller size, new mid-range infrared light-emitting diode (LED) light sources have been developed that allow NDIR sensors to operate at much lower power levels. Combined with a photo-diode light detector, these solid-state sensors also provide a much longer life-span. For example, many modern day sensors now consume only 3mW of power, while typical incandescent IR sensors ...

NDIR Gas Sensors - Electrical Optical Components, Inc.

Nondispersive Infrared Gas Detectors An NDIR gas sensor (nondispersive infrared sensors) is a simple spectroscopic device often used as gas detector. It is called nondispersive because the wavelength which passes through the sampling chamber is not pre-filtered. Instead a narrow bandpass (or NBP) filter is used before the detector.

Nichtdispersiver Infrarotsensor – Wikipedia

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 dual-wavelength method NDIR sensors.
