AQI = Highest Sub Index of each of the below pollutants

Ii = (IHI −ILO)/(BHI −BLO) x (CP – BLO)  + ILO


Ii = Sub Index of the respective pollutant

IHI = Corresponding high value of AQI category

ILO = Corresponding low value of AQI category

BHI = Corresponding high value of the breakpoint range

BLO = Corresponding low value of the breakpoint range

CP = the value of the pollutant measured by he sensor
