The Internet of Things (IoT) refers to the network of interconnected devices, objects, and systems that communicate and exchange data with each other through the internet. These devices, often embedded with sensors and actuators, can collect and transmit data, enabling them to interact with their environment and perform various tasks autonomously or with minimal human intervention.

How Does IoT Work?

IoT devices work by collecting data from their surroundings through sensors and transmitting it to a central system or cloud-based platform. This data can then be analyzed and used to trigger actions, provide insights, or facilitate decision-making. The devices can also receive commands or instructions from the central system, allowing for remote control and management.
