How does an NDIR CO2 Sensor Work? |

At the detector end, the remaining light hits an optical filter that absorbs every wavelength of light except the wavelength absorbed by CO2 molecules in the air sample tube. Finally, an IR detector reads the remaining amount of light that was not absorbed by the CO2 molecules or the optical filter. How is the CO2 level calculated?

Why is my Fire Alarm Going Off? | Cove Security

To stop the alarm, you’ll need to air out the area — open windows, turn on fans and vents above the stove, and wave the smoke out from the area near the smoke detector. Once the smoke is gone, reset the device. Dust/Dirt — Along with smoke, this is another common cause for a false alarm. Photoelectric smoke detectors can mistake dust in ...

Sensors - Gases PRO Sensor Guide - Libelium

The IR series of infrared gas detection sensors use the technique of NDIR (Non-Dispersive Infrared) to monitor the presence of hydrocarbons or carbon dioxide. This technique is based on the fact that the gas has a unique and well-defined light absorption curve in the infrared spectrum that can be used to identify the specific gas.

CO2 Sensor Calibration: What You Need to Know |

All carbon dioxide sensors need calibration. Depending on the application, this can be accomplished by calibrating the sensor to a known gas or using the automatic baseline calibration (ABC) method. Both have pros and cons you should know. Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors.

Carbon dioxide sensor - Wikipedia

A carbon dioxide sensor or CO 2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO 2 sensors are infrared gas sensors and chemical gas carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many industrial processes.

Carbon Dioxide Absorbs and Re-emits Infrared Radiation ...

Molecules of carbon dioxide (CO 2) can absorb energy from infrared (IR) radiation. This animation shows a molecule of CO 2 absorbing an incoming infrared photon (yellow arrows). The energy from the photon causes the CO 2 molecule to vibrate. Some time later, the molecule gives up this extra energy by emitting another infrared photon.

5 Reasons Why Your Carbon Monoxide Detector Keeps Going Off

Dec 15, 2018· (Most CO deaths occur during sleep.) A reliable detector monitors tiny fluctuations over a certain stretch of time and shrieks only when the cumulative amount of CO exceeds safe levels. When your detector goes off, it will sound like intermittent beeps. It will keep going off until the CO levels drop, or you push the mute button.

For instance, on the inside, a CO sensor is very similar to a sensor used to measure H2S. The trick is to keep the H2S from reaching the CO sensing electrode. Most substance-specific CO sensors include an internal activated carbon filter designed to remove the H2S and other acid gas interferents before they reach the sensing electrode.
