The phrase “Internet of Things” and its concept originally emerged in a speech given by Peter T. Lewis in September 1985. He characterized the Internet of Things (IoT) as the fusion of individuals, procedures, and technology together with sensor-equipped, connectable items that enable remote status monitoring, modification, and trend analysis of such objects.
Over the years since the emergence of the concept, it has evolved from simple M2M(Machine to Machine) communication via specific networks without any human interference, to sensor networks of billions of smart devices connecting individuals, systems, machines, and various applications over cloud-based networks sharing data with each other.
The Internet of Things, also known as IoT, therefore now encompasses the collective network of interconnected objects and the technology that enables communication between them as well as between them and the cloud.
The Internet of Things technology helps to integrate everyday things with the Internet, these ‘Things’ are called the Internet of Things Devices and aid in operations in various sectors in which they find application.
What Is Internet of Things Technology
numerous technologies make it possible for the Internet of Things to work. The network that connects the devices in an IoT installation is essential to the field, and multiple wireless or wired systems may play this role. Together, a host of technologies come together to make the Internet of Things possible. Some of these technologies may include;
