Calculated Channels
Each Envisor sensor is configured to provide two channels of data, a one-minute filtered average reading as well as a 15-minute rolling average reading. However, some projects require additional sensor channels.

From the dashboard, navigate to the Sensor Config screen for one of the stations and locate the Calculated Channels panel.
Click the Add button.
In this example, we will create an 8-hour average for PM10 readings by typing in a name for the new channel, selecting the PM sensor and the PM10 60 second channel. Then, choose the Average Prior Readings calculation type and type 480 for the count. Check the box for limits enabled if you would like to receive alerts. You can add as many calculated channels as necessary for each sensor.
NOTE: For 1 minute interval calculations, the count will always be the number of minutes, not seconds. Some examples:
10 minute average = 10 count
30 minute average = 30 count
1 hour average = 60 count
8 hour average = 480 count
24 hour average = 1440 count
Note that there are other types of calculations for more advanced functionality.
