Step 1: Measurement
Our proprietary low-cost, highly reliable air quality sensors delivers high quality environmental data in real time. Across specified areas the sensors collect spatial and temporal data on pollutants and environmental conditions. This bottom-up data collected in the field provides a much higher granularity and better data coverage than the public data. We measure all critical pollutants as recommended by WHO: NO2, PM2.5, PM10, Ozone and various environmental parameters.
Step 2: Data Calibration
Hawa Dawa’s artificial intelligence and machine learning approach refines the air quality measurements delivered by our sensors: real time sensor data is cross-calibrated to ensure even more accurate measurements and eliminate cross-sensitivities.
Step 3: Data Output
The data are available via API or conveniently displayed on our Data Management Platform.
The first digitial solution you can trust
When it comes to IoT-based air quality monitoring, data quality can be the boom or bust for this newly emerging field. It is easy to create measurement graphs using low-cost sensors. Truly measuring what you want to measure however – whilst grasping the effects of sensor cross sensitivity, sensor drift, weather influence – requires a whole set up of different skills (find out about our capablities here). As a pioneer in this field, Hawa Dawa masters the balance between providing a reliable, accurate and stable solution whilst being able to offer what we do at scale.
We have undertaken extensive testing with partners such as the Fraunhofer Research Institute, the Technical University of Munich as well as German and Swiss Environmental Protection Offices. This ensures that our affordable, CE certified devices provide the highest possible standard of data quality according to the EC Air Quality Directive 2008/50/EC.
