What is NDIR ? | CO2 Sensors | PRODUCTS | Asahi Kasei ...

Photodiode (Infrared sensor of NDIR CO2 sensor) Since the photodiode is a photo type detector, its response speed is overwhelmingly faster (typ. 2μs) than that of a thermal type detector. Therefore, by incorporating this photodiode into a NDIR gas sensor and combining with LED of an infrared light emitter, the power consumption can be reduced to the minimum.

Carbon Dioxide CO2 Sensor NDIR 1 PPM Resolution | …

20210609· NDIR stands for Non Dispersive Infrared radiation and the carbon dioxide (CO2) sensors are based on NDIR technology. This technique is widely used to detect carbonbased gases such as CO2 that are present in the air. The CO2 gas enters the sensor and light from the Infrared (IF) source falls on CO2 molecules. These molecules absorb some amount of light at a wavelength of µm. This ...


CO2 Sensors Products |

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 01% (010,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.
