The objective of this book is to take you to a speedy scenic tour of the Raspberry Pi, and introduce you to whatever that is great regarding it.
This book is composed as a project overview. By functioning towards completing this project, you will certainly come to be knowledgeable about the numerous elements that comprise the internet growth stack: the operating system, the hardware (including the GPIOs), the application web server, internet server, data source web server, as well as the Python programs language.
You will certainly additionally become aware of Cloud services that you will integrate into your Raspberry Pi-powered web application.
You application will take sensor information as well as make them available to the individual using an internet interface that is built based upon jQuery and also HTML5.
You will certainly need a Raspberry Pi, a DHT22 sensor, a button, an LED, a couple of resistors and a breadboard. If you desire to setup cordless networking on your Raspberry Pi, you will additionally need a USB Wifi dongle.
To earn one of the most from this program, you need to be familiar with standard programming as well as fit with the command line.
This is just what you will certainly learn:
* Setup the very little Raspbian os to the RPi.
* Install the a Python digital atmosphere.
* Install and make use of Flask, a Python-based web micro-framework
* Install and also make use of uWSGI as the application web server for Flask
* Install and also utilize Nginx light-weight internet server
* Use the RPi GPIOs as electronic input and also outputs
* Use a DHT22 moisture and also temperature level sensor
* Install as well as use the SQLite data source
* Use the Google Chart API to produce graphes of the sensor information
* Use JQuery to include interactivity to website
* Use Plotly for visual evaluation of sensor data
* Install and also set up a USB Wifi adaptor for your RPi
To finish the job, you will need these materials:
* A Raspberry Pi, any type of version
* A Windows, Mac or Linux computer system
* A DHT11 or DHT22 sensor
* An 5mm LED
* A breadboard and also jumper cords
* Access to the Internet
* A USB Wifi dongle, if offered
