When thinking about increasing vehicle safety, reducing the number of road traffic victims often comes to mind first. But something less visible causes more than double the amount of deadly victims each year.

Air pollution is a serious threat to human health. According to the World Health Organization, about 90% of the people globally breathe poor quality air ¹. The level of PM2.5, also known as fine particles, is an important indicator of air quality. Fine particles describe particulate matter that is 2.5 micrometer (µm) or smaller in diameter. These fine particles are produced from all types of combustion, including motorized vehicles and industrial processes, and contribute to smog. 

The fact that fine particles are not visible does not mean these are not harmful. As a matter of fact, the smaller the particles in the air, the larger the harmful effect on human health.  Particles smaller than 10 µm are so small that these are not filtered by people’s nose and throat. This means particles end up in the lungs, potentially causing lung and cardiovascular diseases. Your car can protect you and inform you about the level of fine particles in the air inside as well as outside your car.

PM2.5 sensor

The PM2.5 sensor measures fine particles and sends the measurement values to the car. Based on these measurements, the air intake, filtering and recirculation can be regulated in order to improve the air quality inside the car.

Measuring both the interior and exterior air simultaneously provides a real one-on-one comparison between the air quality inside and outside the car. This means an optimal improvement of the inside air quality can be realized. Furthermore, the car occupants can be informed about these improvements and the difference between the air quality inside and outside the car.

In addition to minimizing exposure to fine particles while driving, the system also enables cleaning of the cabin air prior to the scheduled departure time. When stepping inside the car people enter into a clean environment and can breathe without worrying about poor air quality outside.

The sensor combines measurement accuracy similar to expensive lab equipment with competitive pricing and automotive-readiness. As a result the device is also suitable for, amongst others, building and medical applications.

The PM2.5 sensor will be introduced in a passenger car in the first quarter of 2018. The sensor system is available to all parties interested in measuring air quality and protecting people from the harmful effects of fine particles.

Measuring inside and outside air provides the information needed for an optimal air quality improvement strategy.
