How does an NDIR CO2 Sensor Work? |

While some sensors output this as an analog voltage or 420mA signal, some also include an analog to digital converter on the sensor PCB that converts the voltages into serial or RS485 output. Serial output is especially useful for using NDIR CO2 sensors with Arduino or Raspberry Pi microcontrollers.
