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.
May 21, 2016· Checks for Carbon Dioxide (CO 2) concentrations. Maintenance free NDIR (non-dispersive infrared) CO 2 sensor. Indoor Air Quality displayed in ppm with Good (380 to 420ppm), Normal (1000ppm) indication ... เชื่อมต่อชุดแจ้งเตือน SMS Alarm และ ควบคุมอุปกรณ์ทาง SMS ...
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.
Veris CDE - Carbon Dioxide (CO2) Sensor (NDIR, Duct Mount) - The CDE is a non-dispersive infrared (NDIR) sensor designed for measuring environmental CO2 concentration in ventilation systems and indoor living spaces. Its measurement range of 0 to 2000 ppm makes it compliant with ASHRAE and other standards for ventilation control. The CDE Series provides a user-selectable 4 to 20 mA or 0 to …
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).
CM1106-C series is a single beam NDIR CO2 sensor, based on non-dispersive infrared (NDIR) technology with independent intellectual property, which can detect CO2 concentration of indoor air. With auto-calibration, no need of maintaince. With high accuracy, long term stability, small size, it is widely used for ventilation system, air purifier, air conditioner, HVAC transmitter, IAQ monitor, etc.

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!
