Real-time monitoring of the environment gases within the UV-NIR regions

الملخص EN

Indoor air quality and environmental monitoring, particularly during the coronavirus (COVID19) pandemic are vital and in need.

The main purpose of monitoring the air quality is that the infected area may increase the risk of spreading infectious diseases of COVID-19.

Therefore, real-time and non-contact measurements are more necessary for the current situation to monitor the indoor area air quality.

In this study, we propose an optical method for monitoring indoor air quality in fast and accurate tracking of ultraviolet (UV), visible, and near-infrared (IR) indoor atmospheric gases using the natural sunlight and spectrometer.

The proposed method is portable, non-contact, and real-time spectroscopy screening of the Oxygen (O2), Ozone (O3), and water vapour through the analysis of their absorption characteristics.

The absorption peaks and light intensities of O2 at 630 nm, 685 nm, and 758; O3 at 380 nm, 390 nm, 427 nm, 481 nm, 522 nm; and H2O at 718 nm and 820 nm have been monitored at different weather conditions.

Further to provide air pollution’s effect through tracking the absorption peaks and intensity for each gas, the proposed method might help identify the infected area potential of COVID-19 under practical scenarios such as pre-inspection in houses, shops, hospitals, and schools.

The data are of great importance, particularly for population groups and individuals most vulnerable to COVID-19.

Considering factors such as safety, stability, and price, this simple technology is the most suitable for real applications.
