Abstract

Social issues for environmental pollution are continuously increasing globally. Especially, Users require services to measure environmental factors in indoor and outdoor and manage related data effectively and conveniently. According to this demand, sensors that can measure environmental factors in indoor and outdoor have been developed. However, since one sensor is composed of independent module, the interface of output data from each sensor is different. To solve the problem, we propose a customized protocol for low-power short-range wireless communication between smartphone using Bluetooth and All-in-One sensor device board and analyze the performance of the proposed customized protocol by developing program for performance verification of interface with user smartphone through Bluetooth. In addition, we implement a smartphone application using proposed protocol.

최근 범세계적으로 환경 오염에 대한 사회적 관심이 지속적으로 증가하고 있는 추세이다. 특히, 실내외 환경 요소 측정과 데이터 관리를 편리하고 효과적으로 할 수 있는 서비스 요구가 증가하고 있다. 이러한 요구에 따라, 실내외에서 환경 요소를 측정할 수 있는 센서들이 개발되어 왔다. 그러나, 센서는 독립적인 모듈로 구성되어 있기 때문에, 각 센서에서 출력되는 데이터 인터페이스가 서로 다르다. 본 연구에서는, 이 문제를 해결하기 위해 블루투스를 사용하는 스마트폰과 All-in-One 센서 디바이스 보드간 저전력 근거리 무선 통신에 적합한 전용 프로토콜을 제안하고, 블루투스를 통한 사용자 스마트폰과 인터페이스의 성능을 측정하기 위한 검증 프로그램을 개발하여 제안된 전용 프로토콜에 대한 성능을 분석한다. 또한, 제안된 프로토콜을 사용하는 스마트폰 앱을 구현하여 사용자가 요구하는 구체적인 서비스를 제시한다.
