Case Study: Air Quality Monitoring Company achieves real-time air pollution monitoring for smart cities with Promwad

Air quality monitoring system for clean & smart cities

Promwad worked with Air Quality Monitoring Company, which needed a way to help government agencies and commercial organizations monitor air quality more effectively in support of smart cities, eco farms, national parks, and industrial sustainability efforts. The challenge was to create a system that could measure key pollutants and physical conditions outdoors, with reliable data collection for environmental monitoring and decision-making.

Promwad designed a hardware and software solution with outdoor measuring devices that transmit data to an IoT cloud server for analysis, alerts, and a real-time air pollution map. The system supports LoRaWAN 868 MHz / ISM 433 MHz, Ethernet, GSM, and Wi‑Fi, and measures CO, NO2, SO2, O3, PM2.5, PM10, temperature, humidity, and pressure. This enabled Air Quality Monitoring Company to provide near real-time pollution visibility and support environmental control efforts, with defined measurement accuracies for each parameter.
