Various sensor devices has been developed as the wireless Internet and IoT technology are widely used. Recently, open source hardware has evolved for providing various services in IoT environments. However, in comparison to the development of the open source hardware, the development of human resources is missing. In order to solve such a phenomenon, in this paper, we propose a software framework for the embedded software development in open source hardware. The proposed framework provides a fast and intuitive development environment by using the visual programming language and providing fast feedbacks to developers. In addition, we discuss the strengths and weaknesses of the proposed scheme based on the implement on a real board.

In recent times, Internet of Things (IoT) has attracted wide attention, and there are increasing requests for IoT application services. Open-Source Hardware (OSH) utilizes a variety of components that are created through the sharing of hardware design so that others developers can also work on it. The concept of "open source" that attracted attention in the software industry has been applied to the hardware field by the emergence of IoT market. The emergence of OSH that has the advantage of low hardware cost and faster development encourages the idea of a diverse IoT application services. In this paper, we describe an IoT application service system that is developed using the OSH platform Arduino and Raspberry Pi to process collection, exchange, and computation of the environmental information. The overall system architecture and hardware and software components are presented.

Hidden flame detection after allegedly extinguishing a fire cannot be emphasized enough. There are a few commercial hidden fire detection equipments which are imported, but the cost is relatively high. In this contribution, we propose a development of a low-cost, high-performance hidden flame detector using open-source hardware/software. We use Raspberry-pi based hardware board equipped with a TFT touch-screen LCD, a 3G modem, and an attachable battery device altogether integrated in a plastic case fabricated with a 3D printer. The proposed hidden flame detector shows the same performance of a commercial product FLIR E5 while consuming less than a half of the cost.

The era of IoT in which all objects are intelligent and are connected to the internet has been started. In order to establish and activate an IoT eco system, open IoT services platform is very important. In this paper, we develop an open IoT services platform and verified the function by building a testbed. Our platform based on the open source hardware and commercial cloud services such as AWS which is a component of an open service IoT platform.

In this paper, we have proposed and implemented a smart sensor network system based on the Arduino open source hardware. The proposed smart sensor network system is composed of kinds of sensors and open-source hardware based, Arduino, etc. that can handle the measured sensor values. Also the communication modules that can be used to transmit the measured sensor values from the sensor control unit are configured. In the control unit the sensor data such as temperature, humidity, light intensity can be transmit to the main program and the main program will save the data in the DB or transmitting the value of the particular control signal to the control device or the actuator. The user can also check the information in the system using the measured values from the smart sensor networks through the web, or to remotely control a variety of actuators. And it is possible to manage a smart autonomous control over whether and how the proposed system.

When the study on the relationship between the Head-of-Bed (HOB) angle and ventilator-associated pneumonia is performed, the fact that the HOB angle can only be measured intermittently imposes a significant limitation on the study. Therefore, there has been demand for the development of a device that can measure the HOB angle continuously. In this paper, we propose the rapid prototyping of an HOB measurement system using open-source hardware and software. The proposed system helps to maintain the HOB angle at a particular angle by displaying the angle and helps the medical study of pneumonia patients by enabling continuous data acquisition. Firstly, we eliminate the process of making an MCU board by utilizing an open-source hardware mbed LPC1768. Secondly, we reduce the software development time by using libraries and hence enabling the easy use of peripherals. Thirdly, for rapid prototyping, we build the enclosure of the proposed system using a 3D printer. The proposed system can be attached and detached to and from a bed. Therefore, we can attach it to the bed of a patient for whom measurement of the HOB angle is necessary. Finally, we check the measurement performance and the validity of the proposed system through an experiment utilizing an incremental encoder.
