Smart Home System Based on IoT Concept Using Multi-Sensor Communication

The smart home concept is being developed using the Internet of Things (IoT) technology. The smart home concept offers security services such as monitoring dangerous gas leaks and fires, light control, and keyless door lock systems. Previous studies introduced the idea of a smart home system based on IoT depending on security needs and determining the number of sensors. Still, the description of specific devices used needs to be detailed. Thus, a proper design model for a smart home system was required. This paper proposes a prototype design for a smart home concept by integrating multiple sensors. The sensors used in this prototype are the MQ-2 sensor, DHT-11 sensor, flame sensor, LDR sensor, and RFID. The research results show that the multi-sensor integration was successful, and each sensor could function according to its function within a time range from 0.6 seconds to 2 minutes. The prototype can be implemented through mobile-based applications and given quickly and flexibly.
