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 are applicable 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.
