Air Quality Sensor
If the device contains any of the
exposes mentioned in the following table, an Air Quality Sensor service will be created.
Besides the characteristic mentioned in the table, the plugin will also add the required Air Quality characteristic. The table below contains the threshold values for the different properties. If a single sensor supports multiple of the characteristics mentioned in the table, the worst air quality indication will be used for the Air Quality characteristic.
||VOC Density||<= 333||<= 1000||<= 3333||<= 8332||> 8332|
||PM10 Density||<= 25||<= 50||<= 100||<= 300||> 300|
||PM2.5||<= 15||<= 35||<= 55||<= 75||> 75|
Note that these values have been selected based on several graphs found on different online resources. There might be room from improvement, but then again, the Air Quality is just an indication.
