APPLICATIONS
There are a numerous use of these gas sensors. Particularly, using these gas sensors human beings can be saved from potential dangers. Hence the gas sensors play important roles in various sectors, which include industry, medical, environmental applications, and domestic applications for monitoring toxic and flammable gases.
Below table is from: Data from Taylor (1996), Stcttcr et al. (2003), Capone ct al. (2003), etc. HCs hydrocarbons, VOCs volatile organic compounds.
| Field of application | Function | Examples of detected gases |
|---|---|---|
| Environment | Monitoring toxic gases present in the atmosphere, due to industrial emissions (weather stations, pollutionmonitoring) | CO, CH4, humidity, CO2, O3, VOCs, SOx |
| Safety at work | Control of indoor air quality; monitoring toxic gases in a working environment, for instance in a factory where dangerous chemicals are used | Toxic gases, combustible gases, O2 |
| Domestic safety/household application | Detection of poisonous gases or smoke in households, due to accidents such as fires and explosions; intelligent refrigerator or oven; fire alarm; natural gas heating; leak detection; air quality control; air purifiers; cooking control | CO, humidity, CO2, VOCs |
| Safety in car | Car ventilation control; gasoline vapor detection; alcohol breath tests | CO, LPG, VOCs, CH4 |
| Public security | Control of indoor air quality, detection of substances dangerous for the safety of the general public | Toxic gases, combustible gases, flammable gases, explosives, O2 |
| Medical/clinical | Diagnostics(breath analysis, disease detection); point-of-care patient monitoring; drug monitoring; artificial organs and prostheses; new drug discovery | O2, NH, NOx, CO2, H2S, H2, CL2, anesthesia gases |
| Agriculture | Plant/animal diagnostics; soil and water testing; meat/poultry inspect ion; waste/sewage monitoring | amines, humidity, CO |
| Food quality control | Detection of particular molecules, which are formed when food starts to rot and it is no longer good for consumption | humidity, CO2 |
| Utilities/automotive/power plants | Control of the concentration of the gases in the engine and gas boiler, to guarantee the highest possible efficiency of the combustion process. The same concept can also be applied to power plants, as the energy is generated by combustion | O2, CO, HCs, NOx, SOx, CO2, H2, HCs |
| Industry: Petrochemical Steel/Water treatment/Semiconductor | Process monitoring and control; quality control; workplace monitoring; waste stream monitoring; leakage alarm | HCs, conventional pollutants, O2, H2, O3, CO2, CL2, CH4, H2S |
| Defense/military | Detection of chemical, biological, and toxin warfare agents; treaty verification | Agents, explosives, propellants |
| Aerospace | Monitoring of oxygen and toxic and flammable gases in the environment atmosphere | H2, O2, CO3, humidity |
| Traffic/tunnels/car parks | City traffic control and management; air quality monitoring in tunnels or underground parking garages |
