Carbon monoxide detector alarm principle introduction

Carbon monoxide is a toxic gas. It is colorless and odorless. Carbon monoxide is very harmful to the human body. Some rural households closed the doors and windows in the winter to heat the stove. Natural gas, liquefied gas, gas, etc. were not completely burned, and a closed space with an engine and so on would generate a large amount of carbon monoxide. Most people are unaware of carbon monoxide poisoning. Many people have fallen into a deep coma when they were discovered, and some even died. At this time we need a carbon monoxide detector alarm. So what is the working principle of carbon monoxide alarm?

The carbon monoxide detector alarm uses a carbon monoxide sensor to detect the concentration of carbon monoxide gas in the air and convert it into an electrical signal. The magnitude of the electrical signal is related to the concentration of carbon monoxide.

Carbon monoxide alarms are classified according to the sensors used, and are generally divided into semiconductor carbon monoxide alarms, electrochemical carbon monoxide alarms, infrared carbon monoxide detectors, etc .. From the measurement sensitivity, accuracy, stability, and resistance to cross-gas interference, the best performance It is an infrared carbon monoxide detector, but it is relatively expensive and suitable for laboratory use. The civilian ones are generally semiconductor and electrochemical carbon monoxide detector alarm.

The toxicity of carbon monoxide is obvious to everyone, so the importance of installing a carbon monoxide alarm should be understood. After installation, everyone should carefully read the instructions of the carbon monoxide detector alarm. If you have any questions, please contact us.
