In today's rapidly evolving technological landscape, IoT devices have emerged as pillars of innovation, transforming industries and daily life. But what exactly are these devices, and why do they matter?
Definition of IoT Devices
IoT (Internet of Things) refers to a network of physical objects embedded with sensors, software, and connectivity features that enable them to collect and exchange data over the internet. These "smart" devices range from household gadgets to industrial machinery, creating an interconnected ecosystem.
How IoT Devices Work
- Data Collection: Sensors gather real-time data (e.g., temperature, motion).
- Data Processing: Onboard chips or cloud systems analyze the data.
- Communication: Processed information is shared via Wi-Fi, Bluetooth, or cellular networks.
