What's NDIR (Non Dispersive InfraRed)? | CO2 Sensors | …

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.

Low Cost IR CO2 Sensors -

This CO2 sensor module is designed to monitor 0-5,000ppm carbon dioxide levels using a dual beam light source and NDIR sensing technologies. By using the dual-infrared source principle, the CU-1107 sensor compensates for long-term drifts by design. Dual beam detection allows for superior stability and better accuracy over the predicted 10 year lifespan of the sensor. It can achieve equivalent …

Non-Dispersive Infrared, NDIR, Carbon Dioxide Sensors | …

Non-dispersive infrared, often called NDIR, sensors deliver high accuracy and fast response time. NDIR sensors have no contact with the gas, making them more reliable, and are constructed for specific gases so that they are unaffected by other gases. NDIR sensors are the most reliable method for detecting carbon dioxide gas. NDIR sensors are based on infrared spectroscopy, the principal that molecules …
