This paper is about the design of flowerpot management system which allows you to manage the flowerpot more efficiently and conveniently using Internet of Things when you start to grow plants. IoT connects all things to the network to provide various services to users, it has recently been focused on the center of the IT convergence techniques. So by using the realization sensor based IoT technology the need for research and development of IoT technologies were designed for the system. Basically, Device is using soil humidity sensor and Arduino, Android smart phone and smart light bulb. Transmit the humidity value of the flowerpot that measured by the sensor in a wireless communication, by controlling the state according to the value of the humidity, users can be provided a visual information and set up a flowerpot management and plan.

사물인터넷의 발전과 보급에 따라 스마트 농장 산업이 활발히 이루어지고 있다. 하지만 스마트 농장에 사용하는 기존 토양 습도 센서를 스마트 농장이나 화분에 사용하는 것이 부적절 하다는 것을 실험을 통해 입증한다. 이를 해결하기 위해 반영구적 사용이 가능한 토양습도 센서를 개발한다.

토양 습도 센서를 이용하여 화분의 습도를 측정하며 아두이노 상의 모터를 이용하여 화분에 물을 주어 화분의 알맞은 수분정도를 맞춰줄 수 있으며 온도 센서를 이용하여 화분이 자라는 환경의 온도를 측정하여 너무 더워 말라죽지 않게 조절할 수 있다. 본 논문에서는 아두이노(Arduino)를 기반으로 사용자가 키우는 화분에 여러 센서를 장착하여 수집한 수치값에 따라 습도와 온도를 조절하여 화분의 상태를 조절할 수 있다. 그 결과 사용자가 화분에 크게 관심을 기울이지 않아도 성공적으로 화분을 키워낼 수 있을 것이다.

본 논문은 실내 온도, 습도, 조도, 그리고 토양의 습도까지 탐지하여 자동으로 습도와 빛을 조절해주는 스마트 화분을 다룬다. 화분은 일상생활에서 구할 수 있는 화분을 사용했고 다양한 꽃의 생육 정보를 모은 DB를 기반으로 아두이노를 통해서 다양한 센서 값들을 측정하고 모인 센서 값들은 라즈베리파이로 보내진다. 화분에 부착된 다수의 아두이노로부터 온 데이터를 라즈베리파이가 분석하고 판단해서 사용자에게 전달해주고 조치가 필요한 부분은 아두이노에 전송되어 알맞은 처리가 이뤄진다. 이때 다수의 아두이노와 라즈베리파이의 통신은 지그비 통신이며 라즈베리파이와 사용자 간의 통신은 블루투스와 클라우드 서버를 통해 이루어진다.

In this paper, we propose to improve conventional methods, which measure moisture level in the soil and supply proper water by a hand operation. Our system use wireless sensor network between sensor node and host PC. The measurement system measure moisture level by use moisture sensor. The control system control electronic solenoid switch and supply proper water automatically.

The majority of farm managers growing the garden products in greenhouse concern massively about the diagnosis and prevention of the breeding and extermination for pests. especially, the managing problem for pests turns up as main issue. In the paper, we first build a wireless sensor network with soil and environment sensors such as illumination, temperature and humidity. And then we design and implement multimedia pest predication and management system which is able to predict and manage various pest of garden products in greenhouse. The proposed system can support the database with information about the pests by building up wireless sensor network in greenhouse compared with existing high-priced PLC device as well as collect various environment information from soil, the interior of greenhouse, and the exterior of greenhouse. To verify the good capability of our system, we implemented several GUI interface corresponding desktop. web, and PDA mobile platform based on real greenhouse model. Finally, we can confirm that our system work well prediction and management of pest of garden products in greenhouse based on several platforms.

본 논문에서는 솔라셀을 사용하여 외부에서 별도의 전원 공급이 필요없는 식물 생장 모니터 시스템을 제안한다. 식물 생장 모니터링을 위해 필요한 대기 온도, 습도와 토양의 온도, 수분 함유 상태를 측정할 수 있는 센서를 설치하고 원격지로 측정 데이터를 전송할 수 있는 통신 장치로 서버로 전송한다. 적합한 솔라셀의 용량과 충전배터리의 용량을 결정하기 위하여 식물 생장을 측정하기 위한 센서부의 소비 전력과 통신부의 소비 전력을 측정하여 산출된 용량값을 가지는 솔라셀과 충전배터리를 부착하여 실시간 모니터링 시스템을 구축하였다. 본 시스템으로 고부가가치 농업 분야에서 식물 생장 모니터링이 확대됨에 따라 외부 전원이 필요없는 간편한 원격 모니터링 서비스가 제공될 것이다.

Wireless sensor network with wireless sensor nodes which equipped with temperature, humidity, illumination, or soil sensor etc, get a natural environment information and analyze and utilized variety way.these network consist of a short distance wireless communication and multi-hop techniques with multiple nodes equipped low-power wireless transceivers. so the characteristic of the data collected through the wireless sensor network is obtained from compact nodes within a limited range. However, to get a data from the wireless sensor nodes scattered in a wide range, this network needs a wireless transceiver that consumes many power or a lot of intermediate nodes. then, merit of low cost and low electrical energy decrease. To solve this problem, this paper offers environment monitoring system using autonomous mobile robot that collect data from groups of each sensor networks scattered widely.

This paper designs and implements a smart garden system using probabilistic filter algorithm using SLAM that can be used in apartment or veranda. To do this, we used Arduino and environtal sensors, which are open hardware controllers, and designed to control and observe automatic water supply, lighting, and growth monitoring with three wireless systems (Bluetooth, Ethernet, WiFi). This system has been developed to make it possible to use it in an indoor space such as an apartment, rather than a large-scale cultivation system such as a conventional plant factory which has already been widely used. The developed system collects environmental data by using soil sensor, illuminance sensor, humidity sensor and temperature sensor as well as control through smartphone app, analyzes the collected data, and controls water pump, LED lamp, air ventilation fan and so on. As a wireless remote control method, we implemented Bluetooth, Ethernet and WiFi. Finally, it is designed for users to enable remote control and monitoring when the user is not in the house.
