Description

technical field [0001] The invention relates to the field of external equipment for mobile phones, in particular to an air quality sensor and external air quality sensing equipment for smart phones. Background technique [0002] In the current field of air purification, air quality sensors have almost become standard accessories for purification equipment. Air quality sensors are mainly used in various air purification devices and small household appliances. They have extremely high sensitivity to various pollution sources such as alcohol, cigarettes, ammonia, and sulfide. The products have fast response time, stable work, and low prices. [0003] With the development of society and the acceleration of urbanization, air pollution has attracted more and more attention. Almost everyone has one or even several existing smart phones with more and more functions. Besides the commonly used functions, they also have functions such as positioning and step counting. However, the ex...
