Fig. 40From: Building an indoor air quality monitoring system based on the architecture of the Internet of ThingsFuzzy inference. When the CO2 concentration is 382 ppm, the indoor PM2.5 is 39.6 µg/m3, the outdoor PM2.5 is 28 µg/m3, the indoor AQI is calculated to be 112, and the outdoor AQI is 82. At this time, the fuzzy inference results show that the ventilation unit is 1, the air purifier is 0, and the window is 0.5Back to article page
