Abstract
This paper proposed a smart alarm system based on sleep hypnagogia phase. Hypnagogia phase is an almost wakeful phase or mild sleep state. Waking up in this phase causes people to feel refreshed. This phase is indicated by sudden body movements during sleep or changes in position during sleep. This phase can be detected automatically by a Passive Infrared (PIR) Sensor. In this paper smart alarm system designed to wake the user based on the hypnagogia phase. This system is equipped with LED screens, Real-Time Clock (RTC) modules, buzzers, Wi-Fi modules, and Wemos D1 Microcontrollers. Hypnagogia phase is calculated with a sleep phase detection algorithm that utilizes body movement data captured by the PIR Sensor. This system is designed to adjust the alarm time to the best moment based on the hypnagogic sleep phase that has been calculated. Through several tests, the results show that this system can awaken users with a higher success rate than conventional alarm systems.
