Recently, people are paying huge attention to problems caused by indoor air pollution. Also, the need for the system that monitors environmental information for indoor and warns a danger is growing increasingly. In this regard, we designed and implemented environment monitoring system for indoor. In this paper, we describe the system with hardware elements and it's communication method. In order to transfer the data from environment sensors, we use short-range wireless communication in smart phone. The proposed system is possible to know the indoor environment information in installed sensor node. If the risk is found, For the proposed system, there is an advantage that may be appropriate evacuation.

업무의 효율성을 증대하기 위해서는 주변 환경의 개선이 필요하다. 미국 냉난방 공조학회(ASHRAE)에서도 실내 환경이 업무에 미치는 영향을 발표하고 기준치를 제시했다. 이를 바탕으로 TES-1370, TES-1355센서를 이용하여 주변 환경의 '온도, 습도, co2, 소음'을 측정하고, 측정된 데이터를 가공하여 WEBPAGE와 MOBILE-WEBPAGE에서 차트와 함께 어디서든 쉽게 환경을 모니터링 할 수 있는 실내 환경 모니터링 시스템을 구축한다. 개발된 시스템으로 도서관과 강의실의 주변 환경을 모니터링을 했다.

Recently, we have been demanding the comfort of the indoor environment due to environmental problems such as fine dust and yellow dust. In addition it is pursuing the most pleasant indoor environment for humans. In this study, we designed and implemented monitoring systems and mobile applications to enable information such as room temperature and humidity. Open source software and open source hardware are required to design and implement the systems proposed in this study. In this study, the systems implemented used a bluetooth module, a light sensor, and a temperature and humidity sensor. In the future, we expect to be a basic study of systems that can operate dehumidifiers, warm-air fans, fans and humidifiers using motors and optimize indoor environment.

Along with the increase in the standard of living, the interest and awareness level of the public about environmental issues have also gradually increased. Recently, time spent on indoor activities have increased and the need for awareness and demand on methods in improving the quality of an indoor environment has been recognized. The purpose of this study is to sense the environment information through real-time monitoring of the room environment by using the IoT based technology and to maintain and improve the indoor environment to an appropriate level through the developed interlocking controller device. This provides an automatic control system in improving the indoor environment at home and other small areas like general offices in place of the traditional passive interior environmental improvement actions or large-scale facility control system. A status analysis with the relative reference values of the air quality and CO2, temperature and humidity and illumination and noise was applied through transmitting a control signal to automatic control module in accordance with the nine indoor environment standards set to improve the indoor environment.

대부분의 시간을 실내에서 보내는 사람들이 점점 많아짐에 따라서 안전한 실내 생활환경에 대한 관심이 높아지고 있고, 특히 실내 오염원을 감지하여 사전 조치를 취할 수 있는 측정 시스템에 대한 필요성이 점차 증대되고 있다. 이와 관련하여 본 논문에서는 다양한 환경 센서를 활용하여 가정이나 특정 실내공간의 환경정보를 측정하고 실내공기를 관리할 수 있는 '실내 환경정보 모니터링시스템'을 설계하고 구현하였다.

In the era of the fourth industrial revolution, advanced technologies such as the Internet of Things(IoT) and big data are emerging. However, the level of application of IoT to indoor environment is very weak. Therefore, it is necessary to develop a system for analyzing air pollutants or indoor air quality through real-time monitoring using the IoT. This paper implements a system that measures indoor environmental values using Arduino and various sensors, and stores the information obtained from various sensors into a database of server. The information stored in the server was built as a database and utilized in the ventilation system or air cleaner installed in the home or company's room. In the proposed system, it is possible to check the immediate indoor environmental condition through the LED status display of the monitoring sensor module while reducing the cost of the sensor used to implement IoT technology.

In this paper, we propose a measurement system for measuring radioactivity detected in an indoor environment. This is to measure and prevent radiation generated in various spaces such as general house, workplace, and research institutes. Multi-radioactivity sensors are used to measure multiple spaces simultaneously. The measured radioactivity data is transmitted to the PC in real time through ZigBee and monitored. Even with a small amount of radioactivity, it is considered that it must be installed in a place where radiation exposure is expected, such as a laboratory or workplace, for prevention from chronic radiation syndrome.

본 연구에서는 팔당호에 유입되는 북한강, 남한강, 경안천의 6개 지류에 대하여 2009년 6월부터 12월까지 10일 주기로 현장 측정한 10개의 수질평가 항목과 측정시기에 근접한 4장의 시계열 위성영상에 의한 수질분석 기법을 이용하여 RS/GIS에 의한 수질환경 모니터링을 실시하였다. 현장에서는 다항목 수질측정기(DS5, Hydrolab ; 센서장착포트 7개, 측정항목 : 수온, 탁도, EC, LDO)를 이용하였고, 채수를 통해 실내에서 T-N, T-P, BOD, COD, ph, 부유물질(이하, SS)을 측정하였다. 위성영상에 의한 수질인자는 수온, 탁도, SS 등을 선정하여 자료의 정성적 해석을 통해 팔당호의 수질환경 모니터링을 수행하였다. 또한, 위성영상으로 분석한 수질평가 자료는 현장자료와의 상관성을 검토하였으며 회귀분석을 실시하여 수질인자별 분포도를 작성하였다.
