In the age of the Internet of Everything, smart home appliances have realized anthropomorphic intelligence. In addition to automatic control according to the space environment and usage needs, they can also be personalized according to their own usage habits.Many traditional home appliances have been successfully upgraded to "smart home appliances" because of the addition of sensors. From air conditioners, refrigerators, washing machines, to electric kettles, toasters, toasters, coffee machines, etc., sensors can be used to digitize relevant information and functionalize the data results to achieve intelligent product upgrades.
Gases detected by sensors :
Flammable gas: CH4，CH2F2（R32），C3H8（R290），C2H4
Toxic gas: CO，H2S，SO2，NOx &etc.
Volatile organic compound gases: VOC such CH2O, C6H6 &etc.
Other specific functional gases: O3, NH3 &etc.
Sensor applications in home appliances
As people pay more attention to indoor air quality, air pollution in the home environment, as well as peculiar smells during the use of refrigerators and washing machines, have also got more attention. As the core component of odor detection, gas sensor is not only used in air conditioners, air purifiers, range hoods and other products, but also integrated into air boxes for gas detection. As the home appliance industry continues to upgrade towards intelligence, the application of gas sensors will be more abundant.
At present, air conditioners, air purifiers and other equipments on the market have added gas detection modules for volatile organic compounds such as formaldehyde, benzene, and toluene, which are used to link the equipment to automatically turn on the air purification function, while realizing pollution detection and pollution control. There are also some high-end refrigerators that use gas sensors to sense the gas released from spoiled food, analyze the freshness of fruits and vegetables, and even combine AI algorithms to sense odors to achieve the purpose of food preservation or intelligent deodorization.

Cleaning appliances
Cleaning appliances such as washing machines and sweeping robots in the lazy economy have fast product iterations and functional integration has become the general trend. The addition of dust sensors, VOC sensors, temperature and humidity sensors, etc., brings more possibilities for product function innovation and performance upgrade.
Life appliances
Ambient air quality, which is closely related to people's lives, is an important direction in a healthy economy. Various environmental quality sensors can detect PM2.5, carbon dioxide, formaldehyde, VOC, etc. in the air to ensure a comfortable living environment and improve life happiness.
Kitchen appliances
As the smart kitchen moves from dream to reality, healthier, safer and more convenient smart kitchen appliances emerge in an endless stream. The integration of temperature measurement module, flammable gas module, VOC module, and water quality module creates a new kitchen ecology, with innovative and upgraded interconnected technology, to reconstruct the kitchen imagination.
Refrigerator appliances
Smart refrigerators continue to innovate in the cross-border integration of different technologies. The addition of modules such as food freshness, human body induction, and carbon dioxide allows functions such as temperature control, food management, automatic sterilization, and intelligent alarm to continuously refresh the market and reconstruct future nutritional life.
Sensors in smart home appliances
The innovative application of gas sensors in the field of home appliances is being continuously developed with the advent of the Internet of Things era. Not only has the demand increased sharply, but the focus of development has gradually shifted to the field of MEMS sensors with higher technical content. Compared with traditional sensors, MEMS sensors are smaller in size, lighter in weight, lower in power consumption, and easier to integrate, making them more suitable for the development of intelligent electrical appliances.
With the advancement of sensor technology, looking forward to the development prospects of smart home appliances, increasingly diverse applications will create a larger market.
