A Power-Efficient IoT-Based Awakening System for Healthcare

This paper presents a power-saving Internet of Things (IoT)-based gentle awakening system for healthcare. Based on known bio-science indications on the effectiveness of lights and temperatures for wakefulness, the proposed system timely controls bedroom lighting and temperature so as to tenderly wake up a sleeper to reduce sleep inertia. The system also utilizes a scheme of opportune WiFi disconnection and deep sleep activation of the micro controller ESP8266 for lowering power consumption. Experimental results illustrate that the proposed system performs soft awakening tasks and achieves significant energy conservation.
