Abstract
An automated method of detecting measurement inaccuracy in an air quality detection system includes: receiving an air quality measurement from at least two sensors; determining a difference among the received air quality measurements; and comparing the difference to a threshold value. A system that detects measurement inaccuracy in an air quality detection includes: multiple smart residue avoidance and inaccuracy detection (SRAID) devices; and a server. An SRAID device includes: a plurality of air quality detection sensors; a controller able to: receive measurements from the plurality of air quality detection sensors; calculate a difference among the received measurements; and generate a notification if the difference exceeds a threshold value; and a communication module able to communicate with at least one of a server and an air flow controller device.
