CO and CO2 – What’s the difference? |

CO can be a flammable gas in higher concentrations (sometimes referred to as C1D1 or C2D2 environments) and devices to measure carbon monoxide in these concentrations are normally designed to be explosionproof. CO is the most common type of fatal poisoning in the world. CO Recommended Levels. ppm is the current average CO level on the planet

Create Your Own CO Detector DigiKey

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 opamps 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 CrossSensitivities 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 ...
