Turn your iPhone or iPad into the hub of a distributed sensor network with the help of an Arduino microcontroller. With this concise guide, you’ll learn how to connect an external sensor to an iOS device and have them talk to each other through Arduino. You’ll also build an iOS application that will parse the sensor values it receives and plot the resulting measurements, all in real-time.
iOS processes data from its own onboard sensors, and now you can extend its reach with this simple, low-cost project. If you're an Objective-C programmer who likes to experiment, this book explains the basics of Arduino and other hardware components you need—and lets you have fun in the process.
* Learn how to connect the Arduino platform to any iOS device
* Build a simple application to control your Arduino directly from an iPad
* Gather measurements from an ultrasonic range finder and display them on your iPhone
* Connect an iPhone, iPad, or iPod Touch to an XBee radio network
* Explore other methods for connecting external sensors to iOS, including Ethernet and the MIDI protocol

About the author
Alasdair Allan is a senior research fellow in Astronomy at the University of Exeter, where he is building an autonomous, distributed peer-to-peer network of telescopes that reactively schedule observations of time-critical events. He also runs a small technology consulting business writing bespoke software and building open hardware, and is currently developing a series of iPhone applications to monitor and manage cloud-based services and distributed sensor networks.
Summary
This book looks at how to integrate iOS devices into distributed sensors network, both to make use of its own on-board sensors in such networks, but also as a hub.
