Gas Sensor - an overview | ScienceDirect Topics

The gas sensor starts working when gas molecules encounter the sensor's solid receptors and cause a potential difference that is converted into an electrical signal [160]. It allows different kinds of gases such as carbon monoxide (CO), ethanol (C 2 H 6 O), ammonia (NH 3 ), and nitrogen dioxide (NO 2 ) to be detected [59, 60, 90, 91, 139] .

Carbon Monoxide Sensors: How Do They Differ and Why Does ...

May 28, 2021· Let’s do the math: If a CO sensor that is not a CO/H2 low or CO/H2 null sensor is exposed to 100 ppm of H2, the sensor would interpret the 100 ppm of H2 as 22 ppm of CO. This is based on the CO sensor’s cross-sensitivity to H2. A CO/H2 low sensor typically has 5% or less H2 gas cross-interference. Referring to the example above, a standard ...

Operating principle ‐NDIR-type gas sensor

Where T is transmittance, I is the intensity of light passed through sample gas and optical filter, I 0 is the initial light intensity emitted from the source, εis the molar attenuation coefficient, c is gas concentration, and d is light path length.. Because εof target gas and the light pass length d are fixed with an NDIR sensor, gas concentration can be measured by measuring the ...

Carbon Monoxide Vs. Carbon Dioxide: Let’s Compare

Oct 08, 2019· Carbon monoxide, on the other hand, is the result of incomplete combustion. Incomplete combustion happens when there is a limited supply of air, so only half as much oxygen adds to the carbon, forming carbon monoxide (CO = one oxygen atom, CO2 = two oxygen atoms). Unlike carbon dioxide, carbon monoxide does not occur naturally in the atmosphere.
