Co-create the future of your city!

Join us in the effort to empower actions towards sustainable environmental development. Get informed and participate in gathering, analysis and visualization of environmental data to contribute for a better tomorrow.

Map with existing sensors

About is a crowdsourcing platform, which gathers and presents environmental data. Our network of sensor installations and other third-party sources gathers the data and translates them into visual and easy to understand information. You can learn about the pollution, humidity, temperature or noise in your surroundings with just a few clicks. Even better, you can participate in expanding our network and setup your own devices, to enrich the data sourcing.

Participate and help the network grow!

How does it work?

The core of the system is the n-things platform, tuned and customized as It's comprised of several pieces, i.e. containerized building blocks, which are easily scalable, efficient and robust:

TTN Service


TTN Service

The Things Network is an open and global IoT data network that uses LoRaWAN as a base technology. The network is crowd-sourced, created and driven by the local communities. follows the same philosophies for creating and powering local communities, and uses TTN as a main LoRaWAN provider for the communication of its devices.


Wi-Fi Service

For locations where TTN is not available, Wi-Fi devices can be used as a replacement. houses an internal Wi-Fi access service that receives data in this scenario.

The Wi-Fi service uses double key mapping, TLS encrypted communication and extra sanity checks in order to ensure the data is valid and secured.

3rd party Service


3rd Party Service

Additional data sources like other open sensor networks, custom channels, or standardized government owned AQI sensor network, all serve as credible and valuable data input.

The 3rd party service occasionally polls these sources, fetches the information needed and integrates it in the global system.


Data Processing Services

On daily basis, gathers a ton of data. Getting around in this jungle of information and making use of it, is not a trivial task. is equipped with experimental side data processing services that calculate statistics on device an city level, power an early warning system or predict the near future.

Apache Cassandra

Every single measurement received is permanently stored in a distributed data store cluster.

Apache Cassandra is a free, open-source, wide-column store, NoSQL database. It's the perfect companion to as it guarantees ease of distribution, high availability and performance all the way.
