Description: Unplugged devices are those that operate without a direct connection to a power source, often relying on batteries or energy harvesting methods such as solar or kinetic energy. These devices are fundamental in the context of the Internet of Things (IoT), as they enable connectivity and data collection in environments where electrical power availability is limited or non-existent. Their design focuses on energy efficiency, allowing them to operate for extended periods without the need for frequent recharging. Additionally, they often incorporate wireless communication technologies, such as Bluetooth or Wi-Fi, to transmit data to other devices or to the cloud. The ability to operate autonomously not only expands the possibilities for use in various applications but also contributes to sustainability by reducing dependence on conventional energy sources. In an increasingly interconnected world, unplugged devices represent an innovative solution for integrating technology into everyday life, facilitating the monitoring and control of a wide range of systems and processes.
