ชุด CO2 NDIR

How Do CO2 Sensors Work?

How NDIR CO2 Sensors Work. NDIR CO2 sensors monitor and detect for the presence of carbon dioxide based on the absorption of infrared light at a specific wavelength. An NDIR sensor comprises an infrared source, a light tube, a bandpass filter, and a detector. The target gas is determined through the filter wavelength choice.

Basic Principle of NDIR Gas Detection - Heimann Sensor

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).

New Products 8/11/21 feat. Adafruit SCD-41 – NDIR CO2 ...

Aug 14, 2021· Adafruit SCD-41 – NDIR CO2 Temperature and Humidity Sensor – STEMMA QT / Qwiic. The SCD-41 is a photoacoustic ‘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!
