 Smartphone-based air quality measurement gets personal
This article provides insights into new PM2.5 and VOC sensing technologies that enable personal air quality monitoring to improve people’s health and well-being.


By generating accurate, real-time, personalized air quality data, these new sensor technologies will change how we assess the quality of the air around us and enable us to respond accordingly. We will better plan when to be outdoors to adapt our commuting or sports activities. We will manage the air quality inside our homes by controlling ventilation and avoiding particle generation. When adapted on a broader scale, this will also help us to make informed decisions, for example when relocating to a new area or when deciding where to go on vacation. With the increasing awareness to keep the environment and ourselves healthy, the demand for air quality applications will continue to grow in the future.

Bosch air quality sensing technologies are small enough to be used in flat portable devices such as smartphones and low-cost enough for broad adoption – which will deliver noticeable benefits to both the individual and society as a whole.
