We will try and cover many different topics to demonstrate the flexibility of the Raspberry Pi. The main goal of the book is to get you started on this project that you were just not so sure about. What this book covers Chapter 1, Getting Started with Raspberry Pi, will check the basic equipment that we need to use with this book. We will have to look into the other peripherals that we buy and see how the Raspberry works. We then will be seeing how to flash the newest Raspbian image to our SD card. Chapter 2, Preparing the Network, will illustrate how to set up LAN and a wireless connection to our network and connect to the Internet. We will set some network benchmarks and understand some limitations. We will also look into Dynamic DNS hosting. Chapter 3, Configuring Extra Features, will illustrate how to update the software and the firmware of the Raspberry Pi. We will learn about the watchdog and how to buy extra decoder licenses. Chapter 4, Using a Fast PHP Web Server and Database, will illustrate how to set up a fast web server using nginx with PHP, and decide if we want to use MySQL or SQLite.

  • Iot Energy Monitoring of a Refrigeration Installation
    WEENTECH Proceedings in Energy 6 (2020) 88-98 Page | 88 5th Virtual International Conference on Energy, Environment and Economics, ICEEE2020, 18-19 August 2020 IoT energy monitoring of a refrigeration installation José Uslenghi, Angel Sapena-Bano*, Manuel Pineda-Sanchez, Jordi Burriel-Valencia, Ruben Puche-Panadero, Javier Martinez-Roman Institute for Energy Engineering, Universitat Politècnica de València, 46022 València, Spain *Corresponding author’s mail: [email protected] Abstract This paper presents an application for the energy monitoring of commercial refrigeration facility, based on the concept and technology of the Internet of Things. The purpose of this application is to offer support to the activities of energy audits ant to the implementation of energy management systems, where the energy consumption of a facility must be characterized, or the saving measures applied must be supervised. Among the main features offered by this application are the possibility of remotely monitoring the operating conditions of a refrigeration cycle, as well as its energy consumption. Likewise, its Internet connectivity allows the monitoring system to be scaled up and to group the measurements of several refrigeration installations, which transforms this application into a powerful tool for benchmarking. Internet access also allows notifications via e-mail under particular conditions of the operation of any of the facilities. On the other hand, the application has the capacity to collect and to store in a database the measurements taken by the field devices, allowing the generation of historical reports showing the evolution of the operation of the installation. The main component of this application is the industrial gateway, SIMATIC IOT2040, which is used to read industrial communication buses and to connect to the Internet.

  • “Embedded” Con Sqlite
    Bandiera Roberto – Progettazione e Sviluppo Web con CodeIgniter 3 – marzo 2019 Appendice 5 – Uso di un database “embedded” con SQLite La libreria SQLite (https://www.sqlite.org ) consente di creare e gestire un database di tipo relazionale incorporato nella propria applicazione. Il database è costituito da un singolo file che viene agevolmente inserito all’interno delle cartelle dell’applicazione e trasportato assieme alla stessa. Per poter utilizzare il database non c’è bisogno di alcuna installazione o configurazione, ne’ di avere a disposizione un apposito servizio software, aggiuntivo rispetto all’applicazione stessa. Con SQLite si crea, tipicamente, un database pensato per un uso personale, tuttavia SQLite è anche in grado di gestire l’accesso concorrente di più utenti, applicare i vincoli di integrità del database, garantire transazioni con proprietà ACID (Atomicità, Consistenza, Isolamento, Persistenza). Le prestazioni, in termini di numero di accessi simultanei al database, sono inferiori a quelle di un database gestito da un vero server, come MySQL, SQLServer, Oracle; tuttavia SQLite può venire impiegato, oltre che per una archiviazione di dati per uso personale, come quella inserita nei browser web, anche per realizzare un prototipo funzionante di una applicazione multiutente o per effettive applicazioni web di medio-piccole dimensioni, dove non si ha a disposizione un servizio di DBMS o non se ne vogliono sostenere i costi! Si ha anche il vantaggio di poter spostare agevolmente l’applicazione con il suo database da un server web ad un altro. Per una discussione sulla convenienza di uso di SQLite rispetto ad una soluzione client-server tradizionale si veda ad esempio “Usi appropriati di SQLite” (https://code-examples.net/it/docs/sqlite/whentouse ).

    1 Sweetie Framework: Simple but Practical Web Application Development Environment Motoki Miura Department of Basic Sciences, Faculty of Engineering, Kyushu Institute of Technology 1-1 Sensui, Tobata, Kitakyushu, Fukuoka, 804-8550 JAPAN Email: [email protected] Web: http://ist.mns.kyutech.ac.jp/ Abstract—In order to build a web application, understanding of the programming language, database, SQL, and HTTP is indispensable. Therefore, for beginners, the required skills of the web application development are higher than that of the web page authoring. We propose Sweetie framework that can easily learn basic concept of simple web applications and construct them. Sweetie framework is designed to work with Sweetie, a lightweight web development editor that runs on a web browser. By utilizing the Sweetie framework, novice developers can easily handle, retrieve, and display data in the database. In addition, the Sweetie framework provides user authentication and user registration function for practical applications. We have conducted a web application development lecture using Sweetie and Sweetie framework.
