📡IoT

NEW

Also known as: Internet of Things

A network of physical devices embedded with sensors and software that connect to exchange data.

DESCRIPTION

The Internet of Things connects devices—such as sensors, actuators, and appliances—to transmit telemetry and receive commands. IoT architectures span edge gateways, device management, and cloud platforms. Common protocols include MQTT, OPC UA, and CoAP, with time-series storage for analytics. Security is paramount, covering identity, encryption, and firmware updates. IoT enables monitoring, automation, and advanced analytics across industries, from smart homes to industrial systems.
