Environmental monitoring projects have taken off with ubiquitous smartphones and low-cost, amateur-friendly microprocessors like Arduino and Raspberry Pi. This book explores both the gear and the human side of the sensing revolution. You ll learn how networks of people can conceive and build sensor systems, develop best practices for collecting, analyzing, and drawing information from the data, and then use the results to affect real-world issues.
In the process, you ll explore several issues that many hobbyists, makers, artists, journalists, and activists encounter when building a sensor network, such as: how do you power them? What is "good" versus "bad" data, and how do you tell them apart? How do you collect your data: over the air or by hand from each device? And how do you analyze your data effectively and make it accessible to others?
