Gas Sensors Carbon Monoxide (CO) -

Carbon monoxide is a colorless, odorless, toxic gas. It is predominately produced by incomplete combustion of carbon-containing materials. Incomplete combustion occurs when insufficient oxygen is used in the fuel (hydrocarbon) burning process. Consequently, more carbon monoxide than carbon dioxide is emitted.

Gas Sensor | HVAC Systems | Manufacturer

Jan 08, 2019· The most common gas sensors used in HVAC systems are oxygen (O 2) and carbon dioxide (CO 2) sensors. Ambient air is comprised of roughly 21% O 2 and just % CO 2, but a lack of indoor air circulation can dramatically skew the gas composition towards O 2 depletion and CO 2 enrichment. Indoor air quality (IAQ) is a critical factor for our ...

What is a Gas Sensor? Construction, Types & Working of Gas ...

Jun 04, 2019· A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and ...

Why is hydrogen such a big issue for CO sensors? | GfG ...

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%.

How to Stop Carbon Monoxide Detector Beeping or Chirping

Carbon monoxide detectors contain special sensors that detect carbon monoxide levels in the air. The most common one is called an electrochemical sensor. In electrochemical sensors, the device contains a chemical solution with electrodes immersed in it. When the detector senses carbon monoxide, electrical currents in the chemical solution change.
