In recent years significant advancement has been achieved on the domain of assessing air quality and monitoring the condition of asthma based on sensing technology. The pervasiveness of relevant devices could have a powerful impact on enabling patients self-monitoring and increasing public awareness on the air they breathe. In this study, we investigated a variety of different sensors devices relevant to the monitoring of air quality and different devices for assessing the condition of asthma. Our approach at this stage has been based on feature comparison based on product specification sheets and published case studies. We found that there is no standardisation among such devices and that in order for someone to deliver a holistic intervention for the management of a condition like asthma, a significant amount of proprietary effort to integrate third party data and technologies would be required. Such a solution would include both typical air quality sensing and asthma indicators monitoring, but also elements to seamlessly integrate sensed data and logic about the management of the condition.
