An IoT-based smart pillow for sleep quality monitoring in AAL environments

Millions of people suffer from some way of sleep disorder. As a result, their quality of sleep decreases dramatically affecting not only their sleep but also the quality of their day to day life. Waiting lists for receiving a professional diagnose can be very long leaving the patient unable to take precautions to improve their sleep quality. In this paper, we propose an IoT-based sleep quality monitoring pillow that tracks temperature, humidity, luminosity, sound, and vibration. The pillow is able to forward the gathered information to a server through a wireless router with a static NAT configuration. Subsequently, user and medical staff can obtain the information and determine their quality of sleep. Furthermore, they are able to change the actions performed by the AAL system and the respective thresholds of the cushion. Architecture and algorithm of the system list circumstances that can reduce sleep quality and the actions intelligent devices perform to improve the sleep quality of the user. The paper shows the code for data acquisition and pertinent calibration of all sensors.
