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.

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.

Motion Sensor Light Triggering when camera is mounted ...

2020-06-23· I have a motion sensor light over my garage door that has a IR triggered motion sensor. For 5 days I didn’t have my camera plugged in, (which I have mounted directly over the light). For those 5 days the light didn’t come on unless a physical object moved in front of it. I plugged the camera back in and every few minutes or whenever the light was ready it would turn on. This happened all ...

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. The gas concentration can be determined by using a suitable ...

Go Direct® CO2 Gas Sensor User Manual – Vernier

Go Direct CO 2 Gas measures gaseous carbon dioxide levels in the range of 0 to 100,000 ppm by monitoring the amount of infrared radiation absorbed by carbon dioxide molecules. Carbon dioxide gas moves in and out of the sensor tube by diffusion through the vent holes in the sensor tube. The sensor uses a small light to generate infrared radiation (IR). The IR source is located at one end of …
