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.
