In the world of Internet of Things (IoT), the term “things” refers to devices, machines, or objects that come equipped with sensors. These sensors gather, store, and analyze information. When these “things” connect to the internet and a central data server, they can send this data for further processing. This data can then be used to simplify and enhance various tasks
What makes a thing “smart”?
Being able to exchange information is what makes “things” smart, and this happens when they’re connected to the internet. So, a “thing” doesn’t need fancy storage or a powerful computer inside it. It just needs to link up with a powerful storage or computer system.
Why does it matter?
IoT-equipped devices include gadgets like smartphones and laptops to household items like coffee makers, fridges, Google Home, Apple Watches, and Fitbits. These everyday objects are getting smarter by the day as they gather and share data via the internet. For instance, in the energy sector, sensors can monitor lighting, temperature, and energy consumption. By analyzing this data, smart algorithms can efficiently manage energy usage in real-time, leading to significant cost and energy savings. Additionally, IoT plays a crucial role in disaster preparedness by collecting vital environmental information, enabling early detection of events like earthquakes and tsunamis, ultimately saving lives.
The Growth of IoT
The IoT market has witnessed exponential growth in recent years, with billions of devices now connected worldwide. This growth can be attributed to advances in sensor technology, the proliferation of low-cost connectivity options, and increased demand for automation and data-driven decision-making.
