Polludrone
Real-time Air Quality Monitoring
Timiș County Council deployed 20 Custom-Configured Oizom Polludrone Air Quality Monitoring Stations across towns near the Romania–Serbia border to provide continuous, locally distributed pollution data. As part of the INTERREG IPA Romania–Serbia 2021–2027 “Blue Sky – The Solution to Air Pollution” project, the network measures 10+ parameters along with meteorological parameters, streaming data in real time to the Envizom platform.
This network provides a modern, evidence-based foundation for environmental decision-making and cross-border cooperation, directly linking monitoring data to regional action.
The Romania–Serbia border region is shaped by a mix of agricultural activity, road traffic, and industrial processes; each contributes to the depletion of ambient air quality in ways that are difficult to disentangle without dense local measurements.
Before this project, the area lacked local monitoring, making it hard to accurately identify pollution sources or assess their actual impact on the population and the environment.
To address this gap, Timiș County Council established a monitoring network to enable:
A cross-border monitoring network must measure multiple pollutants and meteorological variables simultaneously, remain reliable in outdoor conditions, and provide data to a single trusted platform. Oizom’s air quality monitoring solution - Polludrone was selected to meet exactly these requirements.
Oizom’s Polludrone addresses these needs in a single modular outdoor unit:

Oizom’s innovative technology has redefined environmental monitoring by providing highly accurate and actionable data on various atmospheric parameters. Our offerings include weather stations, pollution tracking, and noise monitoring solutions. With seamless integration into smart city infrastructure, Oizom’s tools enhance decision-making, compliance monitoring, and community engagement towards a greener planet.
A network of 20 Custom-Configured Polludrone stations was installed across the Serbia-Romania cross-border area, forming a distributed network to capture local variations in air quality. Each station continuously samples its environment and automatically transmits data to Oizom's AI-powered platform, Envizom, for real-time aggregation, visualization, and analysis.
To make air quality information easier for the general public to understand, Beam Light was installed externally on the device. Operating on real-time AQI (Air Quality Index) readings, the Beam Light provides an instant visual indication of air quality through color-coded alerts, allowing the general public to quickly assess air quality.
Each station monitors a wide range of pollutants and meteorological parameters:
| Category | Parameters Measured |
| Particulate Matter | PM1 (very fine), PM2.5 (fine respirable), PM10 (inhalable), and PM100 |
| Gases | SO₂ (sulfur dioxide), O₃ (ozone), NO₂ (nitrogen dioxide), CO (carbon monoxide) |
| Meteorology | Atmospheric pressure, temperature, relative humidity, wind speed, wind direction |
By measuring meteorological parameters alongside pollutants, the network can correlate pollutant concentrations with wind speed and direction, which is essential for tracing pollution sources in a region with diverse activities.
The monitoring network has transformed how environmental authorities understand, manage, and communicate air quality across the region. By delivering continuous, highly accurate data, it enables faster responses, deeper insights, and stronger cross-border environmental collaboration.
Continuous Air Quality Visibility
Deeper Environmental Insights
Stronger Cross-Border Collaboration
Greater Transparency & Public Trust
Compliance-Ready Reporting
By implementing this network, Timiș County Council has advanced toward a modern environmental monitoring system. The solution enhances the region's capacity to monitor air pollution, supports data-driven decisions, reinforces cross-border cooperation, and helps protect public health and the environment.
