10,000ppm MH-Z16 NDIR CO2 Sensor with I2C/UART 5V/ ...

Unlike the chemical CO2 sensor(MG811), this NDIR CO2 sensor does not need a constant ON heating element. The heating element inside a chemical CO2 sensor keeps the sensor warm so that the chemical reaction could happen and produce an continuous EMF as the output, which depends on the CO2 concentration. This NDIR measures the concentration of the CO2 by measure the received IR …

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.
