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 ...

CO2 Sensor Calibration: What You Need to Know |

Most of our CO2 products use nondispersive 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 molecule counts. The industry calls this "drift". To combat sensor …

How to Reset Motion Detector Lights | eHow UK

Motion detector lights feature a motion sensor that''s sensitive to electrical surges or power blinks. Occasionally, after a power blink, the motion sensor light will remain in the on or off position. While it''s logical to think that the light fixture is broken, sometimes all that''s required to get it working properly again is for the motion sensor to be reset. Resetting the motion sensor only ...

How to Reset the ECU After Changing an O2 Sensor | It ...

The O2 sensor in your vehicle monitors the exhaust gases coming out of the engine. It determines the amount of oxygen in the gases, which indicates how well the fuel is being burned. The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle''s computer. The ECU then adjusts the airtofuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it. Once you''ve replaced your vehicle''s O2 sensor, you''ll need to reset …

How to Reset an Outside Sensor Light | eHow UK

The sensor light should reset. Test by walking in front of the sensor, if it goes off the sensor has been reset if not, move on to the next step. Turn the circuit breaker back on. If the sensor light is powered by a light switch, make sure the switch is flipped down to the "off" position. Manually reset the sensor light by flipping its light switch on and off rapidly until the light beam stays ...

CO2 Gas Sensor Troubleshooting and FAQs Technical ...

· To calibrate, use a paper clip to press and release the “Cal” button on the sensor. The red LED should begin to flash. If you hold it so long that it is a solid red, you have reset the factory calibration, which is not what you want to do. If this happens, simply press and release again. You may have to repeat this two or three times for the CO 2 value to adjust to around 400 ppm. Remember ...
