On the Deployment of Low-Cost Sensors to Enable Context-Aware Smart Classrooms.

Smart classrooms augment traditional classrooms with sensors, IoT devices and data networks, and have become a promising arena for context-awareness studies. The collection of contextual data opens the door to numerous applications like environmental sensing, one of the most demanded abilities to face the COVID-19 emergency. To this end, this article presents a flexible and autonomous IoT-based platform for environmental sensing using inexpensive sensors in classrooms. Preliminary results prove the feasibility of the proposed platform and allow us to draw several conclusions on aspects to be considered when deploying these sensors in real settings.
