Carbon monoxide is usually a colorless, odorless, tasteless gas, toxic, and can make people appear to varying degrees at higher concentrations.Poisoningsymptoms, harm the human brain, heart, liver, kidney, lung and other tissues, and evenElectroshock sample deathThe minimum lethal concentration for human inhalation is 5000ppm(5 minutes).

Meanwhile, the carbon monoxide molecule is an unsaturated metastable molecule and is chemically stable in terms of decomposition. At room temperature, carbon monoxide does not react with acids, alkalis, etc., but it can form an explosive mixture when mixed with air. When exposed to open flame and high temperature, it can cause combustion and explosion. It is a flammable and explosive gas.

Which environments do we usually live in? In fact, it may exist in many places.COFor example, the use of gas in the kitchen, underground garage (car exhaust), gas water heater, petrochemical sites, fuel incomplete combustion and so on may exist.

SinceCOThe harm is so great that we have to find a way to solve it. Carbon monoxide is a colorless and odorless gas, which is not easy to detect, so it is necessary to contact other tools to monitor the concentration of carbon monoxide gas in the environment in real time. This timeCOThe leak alarm is used, and it is detected.COIf the concentration exceeds a certain threshold, an audible and visual alarm can be issued. Some alarms also have networking functions, which can check the alarm situation at mobile terminals such as mobile phones.

The core component of the gas alarm is the gas sensor, if the gas sensor performance is poor, low reliability, then how can the alarm do well?

Here,recommend a paragraphCOSensorTGS5042, The sensor has the advantages of high sensitivity, long life, and good long-term stability. Moreover, the sensor has a water storage tank, and the purified water stored inside can be consumed by the reaction, so it is less affected by environmental humidity and the output is abnormally stable. It is very suitable for residential and commercial carbon monoxide detector, industrial carbon monoxide monitoring, indoor parking lot ventilation control, fire alarm and other applications.
