Smoke & Gas Sensor

What is carbon monoxide (CO)?


Carbon monoxide or CO is a gas that is poisonous, colorless, and tasteless, produced as a by-product of incomplete combustion of carbon-containing materials. It is undetectable by humans without using detection sensors. This commonly is produced from vehicle exhausts, fuel-burning furnaces, coal-burning power plants, gas dryers, gas stoves, generators, power washers, fireplaces and wood stoves, charcoal grills, water heaters etc.


CO Gas Sensor/Detector


A carbon monoxide sensor or CO Gas sensor is a device that detects the presence of the carbon monoxide (CO) gas in order to prevent carbon monoxide poisoning. CO sensors are designed to measure CO levels over time. It alarms people before dangerous levels of CO accumulate in an environment to safely ventilate the area or evacuate.
