The sensor data can be backed up and stored for ever so that all the logged historical data can be accessed and analyzed. It calculates and displays IND-AQI, as described by CPCD, and generates multiple graphs to show the trends. It can be configured to send alerts and notifications to the registered users whenever any measured parameters crosses the threshold.
