In 2008, more objects became connected to the Internet than persons in the world. The number of connected things probably will surpass 50 billion by 2020, according to projections by Ericsson. It means that our homes, our industrial plants, our cities and natural environments all will be equipped with sensors that help us to improve our lifestyle, and with machines and systems that talk to each other, aka M2M communication. With such an Internet of Things building out, the virtual Internet we knew is becoming truely physical and sensorily. We will collect huge amounts of data from a vast range of disparate sources, including our environment, infrastructures, businesses, automobiles and ourselves. Among the ultimate goals: “With a trillion sensors embedded in the environment — all connected by computing systems, software, and services — it will be possible to hear the heartbeat of the Earth, impacting human interaction with the globe as profoundly as the Internet has revolutionized communication.” – Peter Hartwell, Senior Researcher, HP Labs Libelium, a company of Spanish origin which sells the award-winning Waspmote sensor board and Meshlium Linux router as an open-source electronics platform for the Internet of Things, has gathered a developer community of over 2,000 people around its modular plug-and-play products that allow entrepreneurs and programmers to focus on services and applications. In February 2013, Libelium published an inspirational guide with 57 concrete sensor applications that developers had created in the following 12 domains: Smart Cities, Smart Environment, Smart Water, Smart Metering, Security & Emergencies, Retail, Logistics, Industrial Control, Smart Agriculture, Smart Animal Farming, Domotic & Home Automation, and eHealth.
