Sensor networks

We employ several sensor networks at TNO. One of them is the ILM2 (Innovatief LuchtMeetnet 2.0) network. It consists of low-cost sensors (so-called CAIREboxes) measuring air quality in the city of Eindhoven. The network consists of more than 30 sensors, measuring NO2, PM1, PM2.5, PM10, temperature, humidity, and pressure. On some locations we measure also UFP. Development of the the airboxes is performed by our team.

My role is to take care of the maintainance of the front-end and databases of the interface (https://ilm2.site.dustmonitoring.nl/), co-writing the yearly reports, and data analysis. The latter comprises both the performance of the sensors, as well as the measured air pollution in Zuid-Oost Brabant. In 2022, we paid special attention to the quality control of the NO2 sensors.
