What role do air quality sensors play in smart homes?

Nowadays, sensors have been integrated into many places in life. They can analyze users’ daily behaviors and increase users’ interaction with surrounding matters, such as common motion sensors, temperature and humidity sensors, etc. Through some commonly used smart 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. These applications are inseparable from the work of sensors.
Smart home refers to a lifestyle that connects home devices, systems and networks to achieve intelligent management and control . With the continuous development of smart home technology, air quality sensors have been widely used in the smart home field.
Air quality sensors have the advantages of high accuracy, high sensitivity, and high reliability. It can monitor indoor and outdoor air quality in real time and 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 concentration of PM2.5 , CO2 , TVOC and other harmful substances in indoor air can be monitored in real time , so that air pollution problems can be discovered and solved in a timely manner to protect the health of your family. At the same time, the air quality sensor can also be linked with smart air purifiers, smart fresh air systems and other equipment to automatically adjust indoor air quality.
As people’s attention to health continues to increase, the application scope of air quality sensors is also expanding, and they are also widely used in public places such as schools and offices. At the same time, some smart home manufacturers have also combined air quality sensors with smart speakers and other equipment to realize voice control of air purifiers and other functions, improving the user experience.
Gongcai.com technical engineers recommend the following air quality sensors that can be used in ambient air quality monitoring. The American SPEC Sensors air quality digital output module DGS-Ethanol 968-035 has calibration and temperature compensation output, fast response of less than 30 seconds, simple digital UART interface.
AMS digital metal oxide multi-gas sensors ENS160 and ENS145 , true VOC air quality detection, have industry-leading purity and stability, and provide multiple outputs that comply with IAQ2 signal standards, such as eCO21 and TVOC .
Austria AMS air quality VOC sensor – lAQ-core : Using micro-machining technology (MEMS) metal oxide semiconductor (MOS) process, it can detect a variety of gases, directly digitally output VOC and carbon dioxide concentration values, and can detect alcohols, aldehydes, Aliphatic hydrocarbons, organic amines, aromatic hydrocarbons, carbon oxide CO , methane CH4 , liquefied petroleum gas LPG , ketones, organic acids and other basic substances. It is a sensor product with compact results and high sensitivity for detecting air quality.
