CO and CO2 – What’s the difference? |

The molecular weight of CO is , where the molecular weight of CO2 is This means that the CO2 gas is much more dense than CO. CO2 will collect near floor level while CO will collect closer to the ceiling. OSHA lists danger levels for CO beginning at 35 ppm, and for CO2 starting at a 5,000 ppm time-weighted average.

Create Your Own CO Detector - Digi-Key

Building a CO (carbon monoxide) detector that can alert you to dangerous levels of CO can be done with as little as a gas sensor, an Arduino (or other microcontroller) and some resistors. Adding a few op-amps can boost the sensitivity to measure the amount of CO present in the environment. Expanding on this knowledge, you can build your own air quality monitoring station, and compare your own ...

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 ...

Kohlenstoffmonoxid – Wikipedia

Kohlenstoffmonoxid (fachsprachlich Kohlenstoffmonooxid, gebräuchlich Kohlenmonoxid) ist eine chemische Verbindung aus Kohlenstoff und Sauerstoff mit der Summenformel CO. Kohlenstoffmonoxid ist ein farb-, geruch- und geschmackloses sowie toxisches Gas. Es entsteht unter anderem bei der unvollständigen Verbrennung von kohlenstoffhaltigen Stoffen bei unzureichender Sauerstoffzufuhr.
