Want to know the temperature? Humidity? Noise level? Local radiation?
We can measure that!
Our book features several projects combining open source computer programming and environmental sensors. Each one shows any DIY electronics maker, even beginners, how to build their own gadgets that monitor noise levels, detect electromagnetic interference (phantom/vampire energy drain), measure local, radioactivity, and more.
We also explain how to put your data online on web pages, Twitter, and the crowd-sourcing data network Pachube.
Patrick and I began devising these projects as a means to teach me Arduino and circuit-building. O'Reilly has been an enthusiastic partner in bringing them to the wider world. Now we're looking forward to seeing how people build, hack, and improve upon our original designs.
