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 ...

Carbon Monoxide Sensor Cross-Sensitivities Alcohols, VOCs & Hydrogen Technical Bulletin Cross-sensitivity to gases other than the target gas of interest is a common sensor characteristic, especially among electrochemical sensors. Cross-sensitivities are limited as much as possible by MSA sensor design and filters; however, some key interactions still occur. CO sensors do have some inherent ...

The Theory Behind Carbon Monoxide Electrochemical Sensors ...

2018-10-15· The carbon monoxide sensor consists of three electrodes immersed in a liquid electrolyte (a non-metalic liquid that conducts electricity, usually through acids or dissolved salts). The three electrodes are the working electrode, the reference electrode, and the counter electrode. The most important of these is the working electrode (WE).

Electrochemical gas sensors are widely used in industry. The following is a brief introduction of electrochemical gas sensor related knowledge. Working principle of electrochemical gas sensor. A small sensor is an electrode wetted by a water-borne gel electrolyte (usually sulfuric acid: H2SO4). When the detected gases (such as carbon monoxide: CO or hydrogen sulfide: H2S) enter the sensor and ...

What are Hydrogen Compensated CO Sensors? | Kane ...

The process is a chemical melting pot as the hydrocarbon fuel splits into its constituent parts of hydrogen and carbon. In some circumstances unburnt hydrogen can be present in the flue in relatively low concentrations. Most electrochemical sensors have a cross sensitivity to hydrogen. So if for example there were 1000 ppm of hydrogen present in the flue this might add 100 ppm to the CO ...

How Electrochemical Gas Sensors and Detectors Work

An electrochemical gas sensor is available for just about any target gas, and across a wide range of sensitivities, such as a highly accurate electrochemical CO sensor. Although they are designed to be as specific as possible, most electrochemical sensors will respond in some manner to gases other than the target gas. This is called cross-sensitivity and is a result of the sensor’s ...

Solid-state Electrochemical Gas Sensor: Carbon Monoxide ...

Carbon monoxide (CO) is produced as a poisonous gas. As CO levels increase and remain above 70 ppm, symptoms become more noticeable and can include headache, fatigue and nausea. At sustained CO concentrations above 150 to 200 ppm, disorientation, unconsciousness, and death are possible. This Smoke-100 sensor measures CO level below 100 ppm ...
