The carbon monoxide alarm senses the concentration of carbon monoxide gas in the air and converts it into an electrical signal. The size of the electrical signal is related to the concentration of carbon monoxide. Carbon monoxide alarm is classified according to the sensors used, generally divided into semiconductor carbon monoxide alarm, electrochemical carbon monoxide alarm, infrared carbon monoxide detector, etc. in terms of measurement sensitivity, accuracy, stability and anti cross gas interference, the infrared carbon monoxide detector has the best performance, but it is more expensive and suitable for laboratory use, and the civil one is generally half Carbon monoxide alarm with conductor and electrochemistry.
Semi conducting carbon monoxide sensor is used as the sensing element of semiconductor carbon monoxide alarm, which is required to respond quickly when the constant temperature of the sensing element is about 200 ℃. Therefore, it is necessary to increase the heating wire for it, so it is necessary to provide a relatively large current. When the temperature, humidity or even wind changes greatly, it is not good for its accurate measurement, and it is also easy to be cross interfered by other gases, For example, the interference of alcohol, nitrogen oxide, hydrogen, alkane and other gases is easy to be misreported, but its price is low. The general service life can be up to five years.
