A city without traffic jams is a greener one. To determine exactly which areas of the city with low air quality, so that it can intervene quickly, Orange has integrated on the smart city platform Alba Iulia Smart City, uRADMonitor solution. It equips the intelligent city with sensors for various polluter factors.

The Intelligent air quality measurement solution, tested by Orange in the pilot project Alba Iulia Smart City, consists in the installation of a mobile network to monitor the environment based on the uRADMonitor solution. A number of 15 sensors have been installed and operate at optimum parameters in 15 buses of STP Alba Iulia, equipped with Internet connectivity or access to LoRaWAN.  The data collected in motion, provides information about the level of pollution in the city and the surrounding area. They are transmitted in real time to a dashboard accessible from any Internet connection, providing updated information every minute about the level of pollution and the evolution of pollution over time or from one location to another.

The basis of the solution is several types of hardware devices, of Romanian conception, made in Timisoara. Equipped with state-of-the-art sensors, they are capable of measuring physical and chemical pollutants of the air. Being equipped with Internet connectivity on IoT topology, measurements are synchronized with a dedicated central server. The URADMonitor solution has a novelty in the fact that the sensors are mobile and can draw a map of pollution.

Data can be exported to a team of the “1 Decembrie 1918 University”  within the Faculty of engineering sciences or any other entity interested in the idea of initiating an impact study (e.g. under the license program “Engineering Environment “or master ” Evaluation, monitoring and environmental audit “) at the environmental level in Alba Iulia. Also, data collected can be accessed in real time through an API, as a utility to propose various pollution reduction projects in certain areas of the city or to create other air quality monitoring applications.

The platform can be accessed from here: uradmonitor.com/alba.

The uRADMonitor system, piloted by Orange in Alba Iulia Smart City, is based on a centralised architecture that aggregate in a database prepared for Big Data all information received from the sensors. All of this information can be accessed through an API and are displayed in a Web interface at this time at the uradmonitor.com/alba link. Connecting to this API and using collection data may be subject to the development of dedicated applications. Orange allows any start-up or institutional entity to connect to these sensors and to use data for scientific or public interest.

The infrastructure dedicated to measuring air quality in Alba Iulia is a Big Data solution verified in existing implementations, which allows connecting new sensors to track even greater numbers of parameters. The detectors have a high quality battery and measure a total of 8 parameters of interest in air quality inside and outside

The URADMonitor A3 model uses BME680 from Bosch to measure air temperature, atmospheric pressure, humidity and volatile organic compounds. A high quality laser dispersion sensor is used to detect particulate matter PM 2.5 concentration in the air (particulate matter). The system also comprises an electrochemical formaldehyde sensor, an undispersed infrared sensor to measure the concentration of CO2 in the air and a Geiger SI29BG tube to detect gamma and X-ray ionizing radiation. An internal fan ensures an active air flow in all detection elements to prevent overheating.

The A3 model is designed with different connectivity options: Ethernet, WiFi, GSM/GPRS and LoraWAN. It needs any voltage in the range of 6v-28V and uses about 1 Watt power to be able to run. A built-in speaker can provide sound notifications, configurable through the dashboard. The drive has no output to the monitor, the data can be viewed remotely on a computer or mobile device. The enclosure has mounting brackets, facilitating installation. The URADMonitor sensor connects to the power supply using a DC adapter with the amintitiă voltage above (between 6v and 28V), as well as the Internet router using Ethernet cable. The Internet Router must have DHCP enabled. When powered, URADMonitor becomes an automatic IP via DHCP, and will appear on the map. It is very friendly with the environment, using very little energy to run.

The data collected by the uRADMonitor sensors contributes to the detection of the best known pollution factors in the city.

On the basis of aggregate statistics, possible solutions for limiting the pollution level, for a cleaner environment and a better quality of human life, can be proposed.

With the help of uRADMonitor, citizens can track the impact that traffic has in certain areas or which is air quality in industrial areas. With this data on hand, appropriate measures can be developed to minimize pollution, because a smart city is a city with fresh air.
