2017년 우리나라는 독거노인 130만 시대에 이르렀다. 정부는 독거노인의 안부를 체크하기 위해 생활보호사를 활용한 노인돌봄 기본서비스 사업을 추진하고 있다. 하지만 노인돌보미의 인력 부족과 서비스 이용률 저하로 관리의 어려움에 놓여 있다. 이러한 환경적 제약사항을 개선하기 위하여 본 논문에서는 온도, 습도, 동작 감지, 가스누출 감지 등의 센서를 활용하는 독거노인 모니터링 시스템을 구축하였다. 센서는 주기적으로 노인들의 각종 현황 데이터를 수집하여 서버에 전송하고, 이 데이터를 기반으로 실시간 그래프를 작성한 후 웹을 통해 모니터링하는 체제이다. 모니터링 과정에서 센서가 정해진 값의 범위를 벗어나면 보호자에게 경고 문자 메시지를 보내어 현황을 통보해 주는 기능을 추가하여 독거노인들의 안전 생활을 지원할 수 있도록 설계하고 구현하였다.

In 2017, Korea has reached 1.3 million elderly people living alone. The government is promoting the basic care service for the elderly by using care workers to check the security of the elderly living alone. However, due to lack of service personnel and service usage rate of elderly care workers, it is difficult to manage. To improve these environmental constraints, this study attempted to construct a monitoring system for elderly people living alone by using sensors such as temperature, humidity, motion detection, and gas leak detection. The sensor periodically collects the current status data of the elderly and sends them to the server, creates a real time graph based on the data, and monitors it through the web. In the monitoring process, when the sensor is out of the range of the specified value, it sends a warning text message to the guardian to inform the current situation, and is designed and implemented so as to support the safety life of the elderly living alone.

제안 방법
In this study, the sensor periodically collects the temperature and humidity data and transmits it to the server, and the receiving server stores the received data in the DB. Based on this data, we designed and implemented a low cost and high quality service system that can monitor temperature and humidity, motion detection, and gas leakage through real time graph creation.
To use the gas sensor with the Raspberry Pi, the values can be detected by using the Arduino to read the correct value in a short time or by using the analog‐digital signal converter on the Brad board. In this study, we worked with Arduino to read and drive the correct values. By connecting the Arduino to the USB port and setting the port by setting the baudrate, precise values can be received from the gas module.
It also includes a function to send a warning message to the guardian when dangerous situation data is detected. This study also added the function to know trends by day/month/year by using additionally collected data. Since the warning situation is considered not only the temperature and humidity but also the rate of change, it is possible to preemptively respond to the situation by enabling more precise and various detection of abnormal situation.
This study designed and implemented a monitoring system for the elderly living alone using the Raspberry Pi sensor, which is inexpensive but has excellent performance. It is designed to be able to monitor the temperature, humidity, leakage, or motion detection remotely.
This study designed web pages dynamically to support not only the pages operated in the browser environment of the desktop but also the mobile environment. Therefore, it is possible to monitor whether the temperature and humidity are detected remotely even in a situation where the PC cannot be used, such as outdoors or moving.
대상 데이터
Arduino uno is an ultra small board based on ATmega32P. It consists of 14 digital inputs/outputs and six analog input USB connection port power lines, and includes all that can drive ultra small controllers. When the USB is simply connected, the power will be turned on and simple operation can start [16].
후속연구
In addition, it is expected to be useful not only for the elderly but also for those children who are sensitive to temperature and humidity and susceptible to cold because they require continuous monitoring and monitoring of motion detection. However, if the danger is recognized in a remote site, the system does not include the function of controlling the temperature and humidity leaks by oneself, so future studies are to be conducted so that the system will be upgraded.
