Multi-point air quality data collection method based on WiFi hotspot names

The invention relates to a multi-point air quality data collection method based on WiFi hotspot names. A WiFi module serving as an AP is installed on an air quality sensor. An SSID of the AP contains air quality information and changes along with the air quality monitored actually. When a sampling value changes, an SSID value of the WiFi module is generated and modified according to the sampling value and information about sensor names, ID and the like, the AP is restarted, and an SSID broadcast is turned on after the AP is started. An APP call operating system interface in an intelligent terminal searches for peripheral WiFi hotspot lists through a wireless local area network card. The hotspot information of the air quality sensor is analyzed from the lists, and the current air quality of the sensor is analyzed from the SSID value. As long as an intelligent mobile phone with the WiFi function is used, by means of the APP operating on the mobile phone, air quality values of all collecting points in channel space can be directly read, and the air quality values can change in real time.
