A Design of Portable Solar-Powered Air-Quality Monitor with Cloud-enabled Safety Watch Smartphone APP

摘要

This paper presents a design of portable air-quality monitor device with a hybrid AC-/solar-powered battery module and a cloud-enabled SafetyWatch smartphone APP. The device is sufficiently lightweight to be transported by person or by bike to an outdoor area and powered solely by its own solar panels. Once started, the device automatically connects to a cloud server, then periodically collects and uploads the ambient air-quality data to the server. Meanwhile, the public can access the air-quality data at the server through SafetyWatch smartphone APP.
