Tips: What is NDIR CO2 Gas Sensor?

The infrared carbon dioxide sensor uses the principle of non-dispersive infrared (NDIR) to detect CO2 in the air. It has the characteristics of good selectivity, no oxygen dependence, and long life. It also has serial output and PWM output, which is convenient to use. The principle of non-dispersive infrared (NDIR) detects CO2 in the air and is widely used in various occasions where flammable and explosive gases exist.
