Air Quality Index (AQI) Calculator

The package calculates AQI according to the Indian National AQI Standards. This can change in the future as per standards. This is just first version of AQI calculation and we are still awaiting a very standard and clear way of calculating AQI.

aqi-calculator is an NPM package that allows you to calculate Air Quality Index (AQI) with the help of pollutant concentrations ranging from PM2.5 PM10 SO2 NOX O3 CO.

Why aqi-calculator?

We make use of AQI calculations to power our air quality application (BreeZo) and its API. Therefore, we are making this independent calculator to set the same standard of calculation across all our applications.
