Prana Air CO 2 sensor is based on NDIR (Non- Dispersive Infrared radiation) technology. This technique is widely used to detect carbon based gases that are present in air. The absorption wavelength of carbon dioxide in this technology is um. The infrared radiation is passed through the carbon dioxide gas when it hits the sensor surface.
This digital NDIR CO2 concentration sensor supports MODBUS RS485 serial communications, SDI-12 communication protocols, and is compatible with the wide power supply voltage of 5-16V. It has a built-in calibration functionality and can be widely applied in both indoor and outdoor environments. This product also adopts both single-air-chamber and ...
In continuous operation ExplorIR® NDIR CO₂ sensor delivers two samples/second and consumes only in continuous operation. Even with two carbon dioxide measurements per second delivering low latency and accurate results, it is typically 50 times lower powered than standard NDIR sensors.
Measuring Carbon Dioxide (CO2) Using Non-Dispersive Infared (NDIR) Technology NDIR sensors work using spectroscopy, which pertains to the dispersion of light into its component colors or energies. An example of this is light in the Visible Spectrum (the light humans can see), which is made up of a wide range of wavelengths (~390nm-700nm).

The basic measurement principle is called nondispersive infrared (NDIR) gas detection, which is based on the absorption of infrared radiation at certain gas specific wavelengths in accordance with the Beer-Lambert law. The most common gases that are measured with this NDIR principle are carbon dioxide (CO2), methane (CH4) and hydrocarbons (HC).
The Non-Dispersive Infra-Red (NDIR) measurement principle is the industry-standard method of measuring engine exhaust CO & CO₂ concentration. Conventional NDIRs have response times of 1-2 seconds, and are typically used to measure "bag emissions" where …
Jan 06, 2021· 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 ...
Knowledgebase. NDIR Principle. Non-Dispersive Infra-Red (NDIR) detectors are the industry standard method of measuring the concentration of carbon oxides (CO & CO2). Each constituent gas in a sample will absorb some infra red at a particular frequency. By shining an infra-red beam through a sample cell (containing CO or CO2), and measuring the ...

GasSense NDIR. INFRARED TRANSMITTER. GasSense is an innovative high specification dual channel infrared gas sensor with integrated transmitter for the measurement of CO2, CO, CH4, N2O or hydrocarbons. Featuring automatic temperature compensation, it can be easily integrated into new or existing measurement systems and monitoring instruments.
Many sensors have to be used simultaneously for multipoint carbon dioxide (CO(2)) observation. All the sensors should be calibrated in advance, but this is a time-consuming process. To seek a simplified calibration method, we used four commercial CO(2) sensor models and characterized their output te …
