Enhance Sleep Duration Using Smart Room Based on IoT

The Internet of Things (IoT) is a technology that connects devices to the internet and communicates with internet connection. Many things could be applied to IoT Technology, and the smart room is one of its implementations. Sleeping is the most effective way to rest and regain energy after a day of activity, and smart room can be applied to bedroom to control factors that could affect sleep quality. IoT technology could help to regulate the room so that the factors could be set to an ideal value and help to improve sleep quality. The author uses Arduino Uno microcontroller and NodeMCU ESP8266 to communicate and send data to Thingspeak.com and Blynk. This system reads temperature, humidity, air quality, and light intensity. The sensors used in this research are DHT22 for temperature and humidity, MQ-2 and MQ-135 for air quality, and LDR Photoresistor for light intensity. IoT System is automated to regulate room conditions and meet user needs. This study aims to help the sleep process for people who have difficulty sleeping with the help of IoT devices. The result gives a desirable impact of using IoT, like a user can enhance sleep from 490 minutes to 520 minutes. Therefore, this study has succeeded in increasing sleep duration by as much as 30 minutes by utilizing IoT as a medium for regulating sleep comfort.
