A platform to support the decision-making of public administrations

Challenge & Context

Many cities are facing challenges in the management of sustainable investments and access to grant opportunities which are based on three main issues to which urban planners are exposed:

  • Difficulties to control the regulatory compliance levels, violation of laws and regulations;
  • Lack of a global liveability index and social welfare, a comprehensive understanding of the global situation, the main needs and the best solution to address them;
  • Lack of useful data, evidence-based indicators.

In this context, FIWARE together with the integration of advanced monitoring systems with highly guaranteed/certified data quality, AI-based modelling and forecasting algorithms, as well as the integration of contextual data over dashboards/DataViz are crucial for the support of sustainable investments and are hence expected to be included in the recently-signed EU Green Deal initiative. This initiative establishes a new model of financing and support for cities that are fighting climate change. Under the initiative, programmes such as the Innovation Fund (worth up to 10 billion euros) allocate 40% of the budget at the beginning of a given project, but ensure that 60% of the budget will be allocated later, depending on the results achieved/demonstrated by the projects. Therefore, there is a vital need to ensure evidence-based and data-driven actions. Most importantly, given the European commitment to become a sustainable continent by 2050, with a 55% reduction in CO2 emissions by 2030, it is time to look head-on at climate change and make a serious commitment.

Given such relevant challenges, the HOPU Ubiquitous company (Human-Oriented Products for Urban-environments) provides different services and products, based on the real needs and profiles of urban planners. By relying on the potential of data with technologies such as Artificial Intelligence, the Internet of Things (IoT), and the FIWARE ecosystem, HOPU contributes to sustainable urban design, helping cities to turn into even smarter environments. In addition, HOPU guarantees that the deployments are understandable, intuitive and usable, making the Smart and Sustainable Cities sector more accessible and agile for the city’s entire ecosystem.


HOPU’s services include air quality indicators to ensure that the United Nations’ Sustainable Development Goals can be achieved. In particular, HOPU focuses on helping sustainable cities and communities working on climate actions, here four (4) areas are mentioned:

  • Air Quality index to know the state of air pollution in urban areas;
  • Pollen service to control the particulate matter levels that may affect the population at risk, such as asthmatic, elderly or allergies;
  • Sound level control to assess noise pollution in cities that affect inhabitants’ mental health;
  • People flow measures to analyse crowd impact within the ecosystem.

To offer different high-quality indicator services, HOPU provides high-quality environmental monitoring devices to deploy smart infrastructures that enable the collection of environmental data from urban areas and create specific liveability indicators in order to support smart decision-making processes.

The range of IoT devices used enables the monitoring of air pollutants and greenhouse gases, particulate matter (including pollen, dust, VOCs), weather, noise pollution and people flow, providing relevant environmental data, which is then also cross-checked with external data sources such as private data, open data and satellite data.

These IoT devices designed by HOPU provide accurate data with more than 80% accuracy in environmental monitoring, 98% in sound level monitoring and 90% in people flow monitoring.

This solution uses the FIWARE Context Broker, which is currently part of the CEF Building Block Programme. Following the FIWARE Open Source approach and thanks to the Orion Context Broker, HOPU integrates datasets from different data sources such as energy consumption or water consumption, social media data, health aspects, among others, offering a solution that allows the analysis of all contextual data, and providing simplified indicators for decision-making.

How it works

To offer different state-of-the-art indicator services, HOPU provides high-quality environmental monitoring devices to deploy smart infrastructures that enable the collection of environmental data from urban areas and create specific livability indicators in order to support smart decision-making processes.

Environmental monitoring IoT devices

Smart Spot IoT devices offer a reliable and robust solution to assure compliance and supporting environmental emissions monitoring, and the preventive detection of anomalies.

Data quality/reliability is a critical differentiation aspect with regards to other solutions. Smart Spot offers certified data quality as IEEE P2510, validations by external institutions such as the Environmental Centre (CETENMA), demonstrating an excellent correlation with respect to reference data sources, and a guarantee and certification of calibration for every individually sold system by an accredited calibration laboratory (ISO 17025) by ENAC accreditation body.

Smart Spots are maintained with the (FIWARE-compatible) AI-empowered cloud platform called Homard for the preventive maintenance, fatigue compensation, and optimization of the data quality and calibration evolution.

These devices are a modular and cost-effective solution adaptable for specific needs, supporting reliable and high data quality for environmental monitoring, gases, and toxic substances identification. This is extensible with other contextual parameters such as noise, affluence of people and the relevant data sources for monitoring that support the understanding of the status to enable data-driven and evidence-based decision-making.

Data analysis/visualization

The data visualization is FIWARE-based (, enabling the configuration of alerts, data analysis, dashboards creation, multi-parameters monitoring/correlation, and integration/communication with other systems via MQTT, OPC-UA/Modbus, Open APIs and direct support of existing Smart Cities platforms, based on FIWARE.

Benefits & Impact

The HOPU Smart City solution for environmental monitoring includes the 4 main pillars that an informed decision-making solution must have unified into a single product. These four pillars are:

  1. A final solution adapted to each territory through interaction with the cities themselves. All the HOPU solutions are city-driven and they grow based on the city’s interaction;
  2. Use all available data sources in the territory as a global territory vision, including open data, private data, satellite data and social data from census and statistics;
  3. Simplification and abstraction to reach clear indicators, making the understanding of Big Data for the different urban planners’ profile easier;
  4. Adaptation of indicators to required regulations and parameters that cover the regulatory needs of territories, providing support in controlling and avoiding sanctions.

The Hopu’ solutions have been already successfully deployed in diverse cities, for example Madrid, Cartagena, Onda, Badajoz, Santander and La Palma. Moreover, it has also been deployed in Bruges and Mechelen (Belgium), composing a list of more than 25 cities throughout the world.

HOPU’s experience in the most diverse cities demonstrates the value of this service in the market and how it contributes to the knowledge revolution in the field of environmental health, following the principles of the World Health Organization by creating a system to exploit data for urban health.
