Start solving world issues by beginning small with simple Rasperry Pi projects. Using a free
IoT server tackle fundamental topics and concepts behind the Internet of Things. Image
processing and sensor topics aren't only applicable to the Raspberry Pi. The skills learned in
this book can go own to other applications in mobile development and electrical engineering.
Start by creating a system to detect movement through the use of a PIR motion sensor and a
Raspberry Pi board. Then further your sensor systems by detecting more than simple motion. Use
the MQ2 gas sensor and a Raspberry Pi board as a gas leak alarm system to detect dangerous
explosive and fire hazards. Train your system to send the captured data to the remote server
ThingSpeak. When a gas increase is detected beyond a limit then a message is sent to your
Twitter account. Having started with ThingSpeak we'll go on to develop a weather station with
your Raspberry Pi. Using the DHT11 (humidity and temperature sensor) and BMP085 (barometric
pressure and temperature sensor) in conjunction with ThingSpeak and Twitter you can receive
realtime weather alerts from your own meterological system! Finally expand your skills into
the popular machine learning world of digital image processing using OpenCV and a Pi. Make your
own object classifiers and finally manipulate an object by means of an image in movement. This
skillset has many applications ranging from recognizing people or objects to creating your
own video surveillance system.With the skills developed in this book you will have everything
you need to work in IoT projects for the Pi. You can then expand your skills out further to
develop mobile projects and delve into interactive systems such as those found in machine
learning. What You'll Learn Work with ThingSpeak to receive Twitter alerts from your systems
Cultivate skills in processing sensor inputs that areapplicable to mobile and machine learning
projects as well Incorporate sensors into projects to make devices that interact with more than
just code Who This Book Is ForHobbyists and makers working robotics and Internet of Things
areas will find this book a great resource for quick but expandable projects. Electronics
engineers and programmers who would like to expand their familiarity with basic sensor projects
will also find this book helpful.
