What do light, sound and air flow readings represent on my Geist monitoring device?
These readings are what we refer to as 'reference' or 'unit-less' measurements. They do not represent an actual value such as lumens or decibels, and are used solely as a reference point. Examples of this would be:
Air Flow - 0-20 Still (very little air movement) - 80-99 Rushing (high air movement). These readings are to help see changes in baseline readings to determine if a problem has occurred. An example of this would be: Light - Baseline reading of 20 (dark). Reading spike could indicate a door was opened, or in worst case scenario could indicate a spark or fire.
