Internet of Things with SAP HANA: Build Your IoT Use Case With Raspberry PI, Arduino Uno, HANA XSJS and SAPUI5

Internet of Things with SAP HANA: Build Your IoT Use Case With Raspberry PI, Arduino Uno, HANA XSJS and SAPUI5

About the Book
In this book, we have covered how to work with Internet of Things (IoT) using SAP HANA Native development, SAPUI5, Raspberry Pi, Arduino Uno and sensor interfacing to solve a personal life problem that will keep the course interesting and fun.

In today’s IT industry, companies are staying competitive by adopting new technologies, streamlining business processes and innovating new services to increase productivity and save costs.

Benefits of Internet of Things (IoT)
  • In the logistics and supply chain, the traditional supply of goods is based on established agreements between manufacturers and suppliers. Orders are made in advance and various stakeholders in the supply chain, i.e., assembly lines, manufacturers, and logistics managers, do the tracking.
  • IoT will have a huge impact in environmental regulation and control as well where we will be able to monitor and control the global problem of clean air, global warming, and recycling.
  • It will also provide a connected world where private transportation can talk to each other to create an accident free and best experience for consumer taking care of medical and emotional need while transit.
  • Factories will be able to run in more robust and self-sustain way using so called Industry 4.0.
Estimated Impact of Internet of Things (IoT)
  • In 2010, the number of everyday physical objects and devices connected to the Internet was around 1 billion.
  • Cisco forecasts that this figure will reach to 25 billion in 2015 as the number of more smart devices per person increases, and to a further 50 billion by 2020.
  • In addition, the global economic impact, which IoT will collectively have, will be more than $14 Trillion; if we compare this to the world population, then by 2020 we will have around more than six connected devices per person.
Why You Should Read This Book
In this book "Internet of Things with SAP HANA: Build Your IoT Use Case With Raspberry Pi, Arduino Uno, HANA XSJS and SAPUI5" we explain you what is Internet of things (IoT) and all the steps necessary to create your own basic setup to start your IoT journey.

In the coming time, we are going to see many new standards, application and devices that will make our life easier, smarter and better and this book will give you the headstart in the path to pioneer this amazing and technology.

To put in a very simple way, IoT will be bigger than anything that's ever been done in high tech and IoT projects are not simple to do, therefore consultants and teams who are working in IoT are paid top rates and salaries.

This book is full of information, knowledge, hands-on and real life project experience learning.

Raspberry Pi: Full Stack: A whirlwind tour of full-stack web application development on the Raspberry Pi

The objective of this book is to take you to a whirlwind tour of the Raspberry Pi, and introduce you to everything that is great about it.

Raspberry Pi: Full Stack: A whirlwind tour of full-stack web application development on the Raspberry Pi

This book is written as a project guide. By working towards completing this project, you will become familiar with the various components that make up the web development stack: the operating system, the hardware (including the GPIOs), the application server, web server, database server, and the Python programming language.

You will also become familiar with Cloud services that you will integrate into your Raspberry Pi-powered web application.

You application will take sensor data and make them available to the user via a web interface that is constructed based on jQuery and HTML5.

You will need a Raspberry Pi, a DHT22 sensor, a button, an LED, a few resistors and a breadboard. If you wish to setup wireless networking on your Raspberry Pi, you will also need a USB Wifi dongle.

To make the most from this course, you should be familiar with basic programming and be comfortable with the command line.

This is what you will learn:
* Setup the minimal Raspbian operating system to the RPi.
* Install the a Python virtual environment.
* Install and use Flask, a Python-based web micro-framework
* Install and use uWSGI as the application server for Flask
* Install and use Nginx light-weight web server
* Use the RPi GPIOs as digital input and outputs
* Use a DHT22 humidity and temperature sensor
* Install and use the SQLite database
* Use the Google Chart API to create visual representations of the sensor data
* Use JQuery to add interactivity to web pages
* Use Plotly for graphical analysis of sensor data
* Install and configure a USB Wifi adaptor for your RPi

To complete the project, you will need these materials:
* A Raspberry Pi, any version
* A Windows, Mac or Linux computer
* A DHT11 or DHT22 sensor
* An 5mm LED
* Resistors
* A breadboard and jumper wires
* Access to the Internet
* A USB Wifi dongle, if available

RASPBERRY Pi 2: Advanced Tips and Tricks

RASPBERRY Pi 2: Advanced Tips and Tricks

This book is a deep exploration of the Raspberry Pi device. Most of the complex functionalities offered by the device are explored in a step-by-step manner. The first part of the book is a guide on how you can use the Pi device as a router. The various configurations which are necessary for this have been discussed. This next part is a guide on how to set up GPIO (General Purpose Input Output) for your Pi,. After reading this book, you will know how to use the Pi so as to sense movement.

The various devices which are necessary for this to happen are explored, as well as the interconnections between them. MATLAB and Simulink for Raspberry are also discussed. You will learn how to use these together with the Pi device. The book will also guide you on how to use the Raspberry so as to sense and record temperatures.

Raspberry Pi Bluetooth Serial Terminal, using HC-06 Bluetooth Module.


HC-06 is Bluetooth to UART Converter. This  post show how to config Raspberry Pi 2 running Raspbian Jessie, to connect HC-06 with serial port. Connect and log-in from Windows 10.

Connect HC-06 to Raspberry Pi GPIO connector:
RPi TXD - HC-06 RXD
RPi RXD - HC-06 TXD
RPi 3.3V - HC-06 VCC
RPi GND - HC-06 GND
*make sure your HC-06 is operate on 3.3V, NOT 5V.


By default, HC-06 work on 9600 baud. So we have to edit /boot/cmdline.txt in Raspberry Pi/Raspbian Jessie, to set 9600 baud.

in default:
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

modify (with sudo right) default 115200 to 9600.
dwc_otg.lpm_enable=0 console=ttyAMA0,9600 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait

Then you can connect and login from Windows 10 with Bluetooth.

This video show how to config Raspberry Pi, and log-in from Windows 10 using PuTTY. In this video, Raspberry Pi desktop is Remote Desktop Connection via WiFi. PuTTY run as Bluetooth Serial Terminal.
