Monitoring of indoor air quality has begun at King Khalid International Airport in Riyadh, Saudi Arabia.

Indoor air quality (IAQ) management in public spaces is increasingly important. Airport terminals are considered “hot spots” and IAQ is crucial for the protection of passengers and staff, as well as a key aspect of the passenger experience at the airport.

Working with Hoshan Aviation and Defense, a Saudi firm specialising in aviation and defence systems, Italian company Softech has developed an indoor monitoring system for Riyadh’s King Khalid International Airport. Thanks to a widespread network of IoT-LoRa sensors, airport operators now have real-time data on the level of CO, CO2, H2S, noise, O2 temperature, humidity, PM 2.5 and PM10 and other pollutants in the air of terminals 2, 3, 4, 5 , private 1 and 2.

LoRa, a wireless telecommunications network used all over the world, was chosen in order to guarantee an intelligent, safe, easy to install, low maintenance system, which is also notable for its low energy consumption.

The IoT sensors are manufactured by Softech, and were tailored to the customer’s needs. The company studied, designed and assembled hundreds of sensors, identifying the best performing electronic components, the best materials and creating casings with specific characteristics and equipment. Mounted inside the airport, the sensors will allow constant and precise monitoring of a wide range of factors.

The data will then be transferred to specially developed software, which will allow analysis and real-time visualisation on a 2D or 3D map of the terminals.

The analysis then enables the transformation of data into statistics, graphs and reports that can be exported in various formats for specific uses. An email alert system enables the users to take prompt action when certain thresholds are reached that are considered dangerous for the health of passengers and airport operators.

Reducing any negative environmental impacts is crucial for airport management, but equally important is ensuring that airports are healthy and comfortable places to live and work, Softech said.
