Air quality sensors being tested in Kista

Two companies are measuring air quality on vehicles in Kista. In coordination with our pilot project DELTA, where connected last-mile vehicles are being tested, Edeva and Smart Sensor Devices are measuring both indoor and outdoor air quality.

Smart Sensor Devices is measuring the air quality inside the vehicles. The sensors are also measuring particle concentration, humidity and temperature. The data could be used to make sure the air quality is satisfactory, for both the driver and the passenger.

Measuring outdoor air quality can be a challenge, as it often requires many sensors in different places to give you the full picture. This may be done more efficiently if the sensors aren’t bound to one specific place. This is being tested by Edeva though GPS-positioned sensors.

The basic principle for the sensors are the same as fixed sensors. Measurements are taken of different gases and particles relevant to air quality. In addition to this the sensors are tied in with GPS to provide each sensor reading with a position. This system makes it possible to track air quality of a large area using one sensor box.

– The goal is to provide real-time data about air quality and to cover a larger area, giving better data to determine total air quality. One problem today is that measurements are taken with high quality but with very sparse coverage. As sensors have become less expensive, and the possibility to add technical solutions like GPS positioning, we want to change this and provide better data for environmental analysis, says David Eskilsson, CEO of Edeva.

Measuring air quality and noise levels are also a better way to determine the environmental quality of a city than measuring how many cars are passing at a given intersection. With GPS-positioned air quality sensors mounted to more vehicles moving in the streets, for example public transport vehicles that spend a lot of time in transit, there is a huge potential for getting better data on which to base decisions about improving air quality and the general environment in a city.
