In-Depth: How MQ2 Gas/Smoke Sensor Works? & Interface it ...

Parts-per-million (abbreviated ppm) is the ratio of one gas to another. For example, 1,000ppm of CO means that if you could count a million gas molecules, 1,000 of them would be of carbon monoxide and 999,000 molecules would be some other gases. Internal structure of MQ2 Gas Sensor. The sensor is actually enclosed in two layers of fine stainless steel mesh called Anti-explosion network. It ...

Carbon Monoxide Sensor Cross-Sensitivities Alcohols, VOCs ...

CO sensors can become saturated with target gas CO. If enough CO enters the sensor beyond maximum range (that listed in the instruction manual), the sensor is unlikely to be able to process all applied gas. When this scenario occurs, the electrolyte becomes saturated. A saturated sensor will continue to show high gas readings until the gas can be processed from the electrolyte. If saturation occurs, allow the …

CO2 Gas Sensor Troubleshooting and FAQs - Technical ...

The reason that CO sensors are potentially susceptible to hydrogen (H2) interference is the reaction that is used to detect gas. Hydrogen is actually part of the detection reaction. The relative response to hydrogen depends on the brand and model of sensor. Some commonly used CO sensors show a relative response to hydrogen as high as 60%. (Not GfG sensors, of course!) Sometimes the cross …

Case Study: Hydrogen Gas and False Readings on Carbon ...

Combustible gas detection sensors that are used for the detection of hydrogen from charging batteries are generally considered catalytic-bead type sensors. These sensors can measure a wide variety of combustible gases, and a hydrogen specific sensor will be tuned and adjusted to detect the LEL (lower explosive limit) of hydrogen gas. It is important to remember that infrared or IR combustible gas sensors can NOT detect hydrogen, and should not be used in areas where gas …
