How does an NDIR CO2 Sensor Work? |

NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes through the optical filter. The band of IR ...

How does an NDIR CO2 Sensor Work? |

While some sensors output this as an analog voltage or 4-20mA signal, some also include an analog to digital converter on the sensor PCB that converts the voltages into serial or RS-485 output. Serial output is especially useful for using NDIR CO2 sensors with Arduino or Raspberry Pi microcontrollers. Early CO2 measurement devices
