What does a gas sensor do?
The role of the gas sensor is mainly reflected in the following aspects:
- Detecting gas concentration and composition. Gas sensors are able to detect the concentration of specific components in gases, such as carbon monoxide, gas, gas, freon, carbon dioxide, etc.
- Monitoring and alarming. By converting the gas type and its concentration-related information into electrical signals, information related to the presence of the gas to be measured in the environment can be obtained according to the strength of these electrical signals, thus allowing detection, monitoring, and alarming.34
- Application to environmental protection and safety supervision. In environmental protection and safety supervision, gas sensors play an important role in detecting the emission of polluting gases and toxic and hazardous gases.
- Application in the field of Internet of Things. In the field of the Internet of Things, gas sensors, as an important part of the perception layer, support the concept of the Internet of Everything by obtaining key devices for information on polluted gases in the atmospheric environment.
- In addition, gas sensors can be integrated into various fields such as smart homes, smart agriculture, industrial gas emissions, automobile air conditioning systems, etc., to provide support for improving indoor air quality, smart planting, breeding of the necessary technology, and carbon neutrality in the context of the monitoring of carbon dioxide and other greenhouse gas emissions.
Gas sensor application areas
1, environmental monitoring: gas sensors can detect carbon monoxide, carbon dioxide, formaldehyde, and other harmful gases in the indoor and outdoor air, as well as haze particles and other pollutants in the concentration, commonly used in urban air quality monitoring, but also can be used in homes, schools, offices, hospitals and car space and other places.
2、Industrial safety: used in industrial environments to detect the presence of ammonia, methane, hydrogen sulfide, chlorine carbon monoxide, and other combustible gases and toxic gases, to prevent explosions and poisoning accidents, is widely used in petrochemical, mining, and laboratories and other places, as well as batteries, semiconductors and other areas of manufacturing.
3, food and agriculture: used to detect the concentration of carbon dioxide, oxygen ethylene, and other gases in greenhouse greenhouses and agricultural warehouses, to monitor the growing environment of crops, control the maturity of fruits and vegetables, and assess the freshness and shelf life of food. Can also be used for livestock breeding, for the detection of carbon dioxide, ammonia, and hydrogen sulfide, and other gases in the farm, control ventilation and air exchange facilities.
4, building safety: in residential and commercial buildings, gas sensors can be installed in the building’s gas pipeline, boiler room kitchen, and other locations, for monitoring and detecting gas leaks, and trigger alarms to prevent fire and explosion risks.
