In 2013, city officials in Melbourne, Australia, assigned ID numbers and email addresses to each of the city's more than 70,000 trees. Designers of the city's Urban Forest Strategy program intended for residents to use the addresses to report issues like disease or dangerous branches. However, residents did more than that: they began writing thousands of messages directly to the trees.
They have written heartfelt notes to individual trees to express their love and admiration, to share their memories and to express their gratitude for protection from the sun and carbon dioxide. Sometimes they ask the trees for their views on current events, or write simply to say hello or apologize for their dog's choice of a urinal.
Occasionally, officials respond to emails on behalf of the trees. One day soon, however, Melbourne's trees – fitted with an array of sensors and connected to low-cost wireless communications – could truly speak for themselves, sharing a wealth of data: temperature, humidity, noise levels, carbon dioxide concentrations, glucose levels and motion readings. Such data can be used to preserve and protect the health of urban forests, which play a vital role in improving air and water quality, reducing stormwater runoff, lowering urban ground temperatures, reducing energy use and mitigating greenhouse gas emissions.
Such is the power of the Internet of Things (IoT), a wave of innovation in which billions of everyday objects – not just trees, but trash cans, lampposts, parking spots, traffic signals, roadways, hospital equipment, appliances, manufacturing lines, crops in the field and much, much more – are being equipped with sensors, processors and communication devices to share valuable data across the Internet and, in some cases, to act on it.
At its most basic level, the IoT offers an affordable means to understand and manage real-world things from a distance while giving some things – a thermostat, for example – the data and capabilities they need to manage themselves. As the people of Melbourne have shown, however, once the things in the IoT are connected and given a voice, they become more than just "things." They become part of a living experience shaped by interactions among people, places and objects, among product, nature and life. They become contributors to what beckons just beyond the IoT: the Internet of Experiences.
