Operating principle ‐NDIR-type gas sensor

NDIR gas sensor consist of an infrared source, detector, optical filter, gas cell, and electronics for signal processing. A single light source, dual wavelength type gas sensor has two detectors and two optical filters of different wavelengths which are placed in front of each detector. Infrared light that is absorbed by a target gas passes through the active filter with a particular bandwidth ...

NDIR Sensor for Non-Dispersive ... - Edinburgh Sensors

Non-dispersive infrared (NDIR) sensors. Key to this process is the selection of the correct absorption wavelength for measurement. The wavelengths from the optical source can be separated spatially using prisms or diffraction gratings. This is known as dispersive separation. Alternatively, an optical filter can be used which allows only transmission of the required wavelength. This is a non ...

NDIR Gas Sensors - Electrical Optical Components, Inc.

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. The NDIR sensor is a broadband IR detector using one of the following technologies: Thermopile ...

Basic Principle of NDIR Gas Detection - Heimann Sensor

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.

Signal conditioning for NDIR sensor - Application note

NDIR sensor is generally composed of the infrared source, optical cavity, dual-channel detector and an internal thermistor, as described by Figure 2. NDIR principle. Figure 2. NDIR principle Both channels are made of a thermopile, one is considered as a reference and the other one is considered as the active channel. Each channel has a specific wavelength filter. The active channel has a ...

Adafruit SCD-30 - NDIR CO2 Temperature and Humidity Sensor

2021-07-25· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...
