In the new era of technology, healthcare protection is shifting from traditional methodologies to predictive and preventive aspects. This can be achieved by a prolonged and comprehensive effective health parameter observation. Ambient air monitoring, activity measurements or critical physiological and vital signs evaluation might be embedded in this category and construct the ambient assisted living (AAL) environment. Due to the importance of environmental parameter monitoring in health, in particular with an adverse impact on patients, children and elderly, a prolonged personalized ambient air monitoring is a crucial part in healthcare protection. In this work a suitable wearable device within IoT platform is proposed. The wearables for evaluation of the most important indicators in healthcare construct the first tier as wireless sensor network (WSN). For a sustainable monitoring, data protection and analysis, these data are transmitted to a cloud via a gateway (e.g. smartphone). In this paper, we design, implement and justify a personalized wrist-worn system for ambient air monitoring. The major focus of this work is nitrogen dioxide (NO 2 ) evaluation in a realistic laboratory environment. |
