temperature wherever a sensor unit is located. A green light emitting diode (LED) on the central unit indicates normal safe conditions. If ambient conditions at the sensor unit reach a CO2 concentration level of % (preset low alarm), the central unit will emit an intermittent audible tone and the « low alarm » red LED will blink. If equipped, a remote warning lamp will be activated. This ...

CRIR E1 Commercial Carbon Dioxide Sensor User Guide

As the light passes through the sensing chamber, a fraction is absorbed if CO 2 is present. The difference between the light emitted by the source and received by the detector can then be converted to a CO 2 concentration reading. The Automatic Baseline Correction (ABC) function can automatically calibrate the sensor’s lowest reading over a pre-configured interval to 400 ppm CO 2. This ...

Sensors - Honeywell

Lighting Sensors. The Analog Light Sensor is a precision electronic sensor that responds to ambient light levels and provides a variable milliamp output signal. It uses an accurate photo diode device with a color-correcting filter to provide a spectral response approximating that of the human eye. The solid-state, light-sensing element is located within the metal case of the sensor. Wall ...

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 ...

CO2 Sensor Calibration: What You Need to Know |

Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors. These rely on an infrared light source and detector to measure the number of CO2 molecules in the sample gas between them. Over many years, both the light source and the detector deteriorate, resulting in slightly lower CO2 …

CO₂ sensor - Infineon Technologies

The CO 2 molecules inside the measurement chamber absorb the filtered light, causing the molecules to shake and generate a pressure wave with each pulse. This is called the photoacoustic effect. The highly sensitive MEMS acoustic detector detects the pressure change generated by CO 2 molecules within the sensor cavity, and the microcontroller converts the output into a CO 2 concentration ...
