Analysis of Single Board Architectures Integrating Sensors Technologies

Abstract

Development boards, Single-Board Computers (SBCs) and Single-Board Microcontrollers (SBMs) integrating sensors and communication technologies have become a very popular and interesting solution in the last decade. They are of interest for their simplicity, versatility, adaptability, ease of use and prototyping, which allow them to serve as a starting point for projects and as reference for all kinds of designs. In this sense, there are innumerable applications integrating sensors and communication technologies where they are increasingly used, including robotics, domotics, testing and measurement, Do-It-Yourself (DIY) projects, Internet of Things (IoT) devices in the home or workplace and science, technology, engineering, educational and also academic world for STEAM (Science, Technology, Engineering and Mathematics) skills. The interest in single-board architectures and their applications have caused that all electronics manufacturers currently develop low-cost single board platform solutions. In this paper we realized an analysis of the most important topics related with single-board architectures integrating sensors. We analyze the most popular platforms based on characteristics as: cost, processing capacity, integrated processing technology and open-source license, as well as power consumption (mA@V), reliability (%), programming flexibility, support availability and electronics utilities. For evaluation, an experimental framework has been designed and implemented with six sensors (temperature, humidity, CO2/TVOC, pressure, ambient light and CO) and different data storage and monitoring options: locally on a μSD (Micro Secure Digital), on a Cloud Server, on a Web Server or on a Mobile Application.

IoT Clusters for Enhancing Multimedia Applications

“…For the implementation of the framework, we used Elixir programming language [ 29 ] because of the ease it provides to distribute and execute data and code by devices in a network. For the hardware, we used Raspberry Pis, a type of SBC (single-board computer) that can be used as a generic IoT device and enjoys enormous popularity due to is high performance for its price range and the vast number of scenarios where it can be used [ 6 , 7 , 8 ]. The use of this type-o SBC also allows the use of Linux as the operating system to implement a resource reservation policy and use Elixir along with the Erlang virtual machine [ 30 ] in each one of them, creating a distributed scenario that is simpler to manage.…”

“…The single-board computer (SBC), a rather powerful type of machine that can be used as a generic IoT device, enjoys enormous popularity due to their high performance for their price range and the vast number of settings wherin they can be used. These devices are becoming a standard for IoT prototyping and implementation [ 6 , 7 , 8 ], bringing more and more computing power to this domain and also more underutilized devices.…”

Context-Aware Edge-Based AI Models for Wireless Sensor Networks—An Overview

“…As new wireless technologies such as WiFi Direct, 5G, Zigbee, LoRa, NB-IoT and LiFi are rapidly being developed, Edge Computing (EC) will soon help transition processing and analysis from the cloud to the edge [ 15 , 16 , 17 ].…”

Integration framework for sensor through IoT embedded microcontroller in automation system for hydrogen generator management

“…Continuous monitoring and logging of the temperatures of a photovoltaic generator is solved by Arduino and digital sensors in [17]. The integration of sensors by means of single-board architectures, like Arduino, in different scenarios is reviewed in [3], which shows the wide applicability of this type of systems.…”
