ThingsLog public portal for Air Quality monitoring for a Bulgarian municipality

ThingsLog has recently realized a Public portal for air quality monitoring for the municipality of Yambol – an administrative center of a province in Bulgaria. It is intended to allow the public constant monitoring of the air quality.

The Challenge

Stricter regulations and public pressure make air quality monitoring more and more important for municipalities. Based on medical studies air pollution may be linked to lung cancer, chronic pulmonary illness, respiratory infections, and heart disease. Thus, the municipality administration decided to introduce a solution for real-time monitoring of air quality in the town and to control and manage the sources of pollution.

Solution

ThingsLog Air Quality Monitoring system is a full solution for monitoring and regulatory compliance in urban areas, contributing to a safer and healthier environment. The system is simple to set up based on flexible monitoring stations with customizable sensors. 

With this implementation, the city is split into sections, and the first air quality monitoring stations were put in the most vulnerable regions – in the city’s industrial core and in densely populated areas such as schools, universities, and parks.

The monitoring stations collect data every 5 minutes and send the measurements every 15 minutes. The data is kept on the ThingsLog cloud-based platform after being delivered over a LoRa WAN wireless communication protocol.

Things Log application presents the city map at a glance with all stations marked. When a specific station is selected, the citizens see the air quality parameters from that station. The color of the station symbol on the map changes from green – yellow – red depending on the level of pollution. The portal is integrated into the Municipality’s official website and is available to citizens.

Particulate matter (PM1.0, PM2.5, PM4.0, and PM10), air temperature (0C), air humidity (%), and radiation (cpm) are all monitored by our air quality system. If necessary, the monitoring station may be simply expanded to include additional air monitoring characteristics such as Ozone (O3), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), and Carbon Monoxide (CO) emissions.

Benefits and outcomes

Real time Air Quality Monitoring system with data collection and storage. Possibility of alarm notification of any of the parameters exceeds the normal values.

Quick identification of air pollution sources – just by look on the station symbol color on the map, you can detect air pollution source in a certain area relatively quickly. This will assist regulatory authorities in taking appropriate measures against industrial pollution sources that release harmful substances at night when control is challenging.

The data is stored in our Cloud Based Server, and customer has access to his air pollution profile. The stored data may be compared to previous periods, and this will help evaluate the pollution reductions activities taken by the responsible authorities in the area.

Public information on air quality and hazardous areas to avoid, as well as increased public supervision over antipollution measurements carried out by the municipality.
