Indoor air optimization method for intelligently controlling air purifier according to air quality

The invention discloses an indoor air optimization method for intelligently controlling an air purifier according to air quality, which comprises the following steps: collecting indoor air quality parameters including indoor PM2.5 content, indoor CO2 content, indoor HCHO content and indoor TVOC content; according to the indoor air quality index obtained through calculation, the purifier equipment is automatically turned on or turned off, and gear adjustment is carried out. Wherein the maximum value of the four quality indexes X obtained through calculation is taken as the current indoor air quality index. The indoor PM2.5 content, the indoor CO2 content, the indoor HCHO content and the indoor TVOC content are fused together for calculation, so that the calculated result can better reflect the current indoor air quality, then the purifier equipment is automatically turned on or turned off and subjected to gear adjustment according to the indoor air quality index obtained through calculation, and the indoor air
