What role do air quality sensors play in smart homes?

Nowadays, sensors have been integrated into many places of life, which can analyze users’ daily behaviors and increase the interaction between users and surrounding affairs, such as common motion sensors and temperature and humidity sensors. Through some commonly used intelligent sensors, the convenience and safety of life can be greatly improved. Among the popular smart home product designs, there are designs for air purifiers, harmful gas detection and other works, and these applications are inseparable from the work of sensors.
Smart home refers to a lifestyle that connects home equipment, systems and networks to realize intelligent management and control. With the continuous development of smart home technology, air quality sensors have been widely used in the field of smart home.
The air quality sensor has the advantages of high precision, high sensitivity and high reliability. It can monitor indoor and outdoor air quality in real time and give an alarm in time. In addition, the air quality sensor can automatically adjust indoor ventilation and air purification to ensure indoor air quality.
By installing air quality sensors, the concentrations of harmful substances such as PM2.5, CO2 and TVOC in indoor air can be monitored in real time, and air pollution problems can be found and solved in time to protect family health. At the same time, the air quality sensor can also be linked with intelligent air purifiers, intelligent fresh air systems and other equipment to automatically adjust indoor air quality.
With people’s increasing concern for health, the application scope of air quality sensors is also expanding, and they are also widely used in schools, offices and other public places. At the same time, some smart home manufacturers also combine air quality sensors with smart speakers and other devices to realize voice control of air purifiers and improve user experience.
The technical engineer of industrial and mining network recommended that the following air quality sensors can be used in ambient air quality monitoring: American SPEC Sensors air quality digital output module DGS-Ethanol 968-035, calibration and temperature compensation output, quick response less than 30 seconds, and simple digital UART interface.
AMS digital metal oxide multi-gas sensors ENS160 and ENS145, real VOC air quality detection, have good industrial purity and stability, and provide multiple outputs that meet IAQ2 signal standards, such as eCO21 and TVOC.
Austrian AMS air quality VOC sensor-lAQ-core: The metal oxide semiconductor (MOS) process with MEMS technology can detect a variety of gases, and the direct digital output of VOC and carbon dioxide concentration can detect basic substances such as alcohols, aldehydes, aliphatic hydrocarbons, organic amines, aromatic hydrocarbons, carbon monoxide, methane CH4, liquefied petroleum gas LPG, ketones, organic acids, etc. It is a compact and sensitive product.
