Overall Indexing of Indoor Air Quality: a New Method of Evaluating Indoor Air Quality Based on Gas Sensor Array

摘要

A simple, cost-effective and highly-efficient way is proposed to measure and evaluate data in real-time, where the concept of overall indexing of indoor air quality is introduced and the metal-oxide gas sensor array is adopted for air quality evaluation. Results from the 'indoor air quality detection and control' demo system prove the superiority of the proposed approach over conventional methods in the above-mentioned aspects.
