Internet of Things Technology

  Internet of Things(IoT)

The Internet of Things (IoT), also known as the Internet of Everything (IoE), is the interconnection via the internet of computing devices embedded in everyday objects, enabling them to send and receive data.

---

The IoT is a system through which any device or other item — whether connected to the internet or not — has the ability to collect and exchange data with any other device. These items are able to “talk” to one another either over short distances using radio waves, like Bluetooth, or over long distances using IP (Internet Protocol). If you think the idea of your car being able to track what’s in your refrigerator is science fiction? Think again! The IoT technology constitutes the connection of our everyday items with the internet, allowing for their identification by all the other devices on the network. This technology is revolutionizing the making industry by collecting data from all of the connected devices of the customer and tailor marketing their products to better meet customers’ needs. The IoT sensors are also used in the field of agriculture, by allowing farmers to better monitor soil attributes and make informed decisions like the need for fertilization and irrigation of their farms.
