AsthmaWatch pollution data and pollen forecast for Stockholm

Air pollution induced respiratory diseases are rapidly increasing in large cities. Treatment of diseases caused by air pollution is estimated to cost approximately 2% of GDP in developed countries and 5% in developing countries. AsthmaWatch, developed in the GOEASY project incorporates a Galileo based secure mobile air quality monitoring platform into a mobile smartphone app that enables users to identify places and pollutants that they can avoid. Every day outdoor air quality changes on a street-by-street basis. By crowdsourcing air quality information from mobile sensors, the app helps citizens proactively avoid unhealthy environments.

Pollution varies in location and distribution strongly related to the weather and people suffering from Asthma or from pollen allergies can use detailed forecast data to avoid highly polluted areas to avoid negative impacts on their health. AsthmaWatch visualizes measured pollution for the Stockholm area providing detailed forecasts and rout recommendations based on pollution data:

New generation of GoEASY field kit

CNet has developed a Sensor field kit to monitor air pollutants within urban areas. The field kits can measure different pollutants and transmit their location where the measurement is taken to visualize the current level of different pollutants within the area. The data is stored and the GoEasy App can visualize historical readings at different points-of-interest. The new generation of field kits can measure small and larger particles as well as NO2 and are can be used walking, cycling or motorized modes of transportation. The field kits run on an external batteries which enables measuring and transmitting data for several days. The new generation of field kits will be deployed in a Pilot in Stockholm collecting data to generate a pollution map of the city.

GoEasy improves life for asthmatics using Copernicus forecast data

GoEasys AsthmaWatch app combines Galileo satellite positioning data with live air quality monitoring data to offer people with asthma and other lung-related diseases a fine-grained air quality map of their city. As basis of several services of AsthmaWatch like early warnings of areas with low air quality, best route selection regarding pollution, current and historic pollution rendering at specific points of interest, aiming at improving life quality for people with asthma and other lung-related diseases.

The GoEasy data collection platform was extended to include data from the Copernicus Atmosphere Monitoring Service (CAMS). CAMS is one of six services of Copernicus, the European Union’s Earth observation programme, which is based on a set of satellites and ground-based observation stations. Data from CAMS is available as Gridded Binary (GRIB) files, a standard used in meteorology. It provides weather data up to three days into the future. In GoEasy we have developed advanced translation software to translate GRIB data into a JSON-based format like OGC (Open Geospatial Consortium) so that the complex GRIB format can easily be integrated and used in any IoT application. The AsthmaWatch smartphone app already showed the current level of different pollutants and visualized historical readings at a certain point-of-interest. Now it has been extended to also provide users with an instant 3-day forecast, including 8 different pollens, 5 pollutants, solar radiation and temperature.

CNet launches GoEasy mobile IoT sensing gateway

The first version of the GoEasy mobile IoT sensing gateway is now available. It is equipped with a Galileo-receiver, an air quality sensor, a sound level sensor and a communication chip.

The gateway is designed to be mounted on bicycles and electrical scooters. The sensors in this gateway continuously measure the NO2 level and the sound level. The measurements are transmitted using NB-IoT (Narrow-band IoT) to the GoEasy cloud. The Galileo chip gives the precise position where the measurements are taken while the vehicles are moving. The GoEasy gateway run on battery or can be powered through a USB Connection to an electrical bike or scooter battery. When a sufficient number of vehicles are collecting data in the city, GoEasy will be able to create a complete air and sound pollution map in realtime over the city. This data will form the basis for development of a new generation services for citizens.

The first service is AsthmaWatch, which will help and guide asthmatic people to avoiding polluted areas in the city. A first test of the GoEasy gateway will start during May in the cities of Copenhagen and Stockholm.

MyAirCoach presents asthma monitoring system

The MyAirCoach project has developed a mobile health device and sensor-based approach connected to a patients mobile phone that measures asthma indicators and collects information to support patients and healthcare professionals. Through monitoring asthma indicators and collect a patients physiological, environmental and behavioral information, it helps patients and healthcare professionals to control the effectiveness of asthma treatment and to prevent severe asthma attacks.

CNet developed a mobile app within the project, that enables to use available indoor and outdoor measurements of asthma indicators to assess the air quality and the personal risk to experience an attack. The analysis of the personal risks can aid patients in their self-management and help to avoid severe asthma attacks.

“The purpose of the app is to make life a little easier for asthmatics in Stockholm,” says Peter Rosengren at CNet.

For people with asthma, their inhaler plays a central role in managing the condition. These simple drug delivery devices have been used for decades to deliver medication to the lungs. Regular treatment with inhaled controller medication helps to keep asthma under control and, for some patients, ‘rescue’ or relief medication can limit the impact of an exacerbation (or ‘asthma attack’). The myAirCoach consortium, where CNet is a member, has been working to extend the utility of inhalers by developing adaptors to make inhalers smarter to improve outcomes for patients. Companies, hospitals and universities – in collaboration with patients – have been working to improve inhalers so that we can get as much information as possible about how the patient uses their device and information about the state of the lungs and the immediate environment.

CNet wins the Open Stockholm Award with AsthmaWatch!


Yesterday the final in the Open Stockholm Award took place. In total 220 contestants were competing for this prestigious award, and the jury selected our innovative solution AsthmaWatch as the winner! The motivation is that “AsthmaWatch shows a highly innovative use of the city’s open data sources and helps people live a better life”. AsthmaWatch combines IoT sensors and open environmental data to guide asthmatic persons in their daily life to avoid exposure to bad air quality.

Air Quality app available in AppStore

We have launched an iOS app, Open Stockholm, that shows the outdoor air quality and other environmental parameters in different places in Stockholm. The current level of different particles like PM10 and PM2.5 as well as the level of NO2 and Ozone is shown as well as historical values during the day. The app is freely available in AppStore. Search for “Open Stockholm”.
