Five Internet of Things (IoT) devices used in the study. (1) Human sensing LED lighting (entrance ceiling) senses user’s motion and turns on the light, (2) Occupancy sensor (door) also detects user’s movement, (3) Remote controller has buttons for turning on/off the lights and making SOS call, (4) Wall switch can turn on/off the light and send usage log to communication module in LED lighting, (5) Automatic gas circuit breaker blocks a gas flow when an individually set time passes. Data (usage log of LED lighting, measurement value of occupancy sensor) from all devices except the automatic gas circuit breaker, are all gathered in communication module of LED lighting, and sent to a main server every 5 min without a personal home wired or wireless network. LED light emitting diode.
