IoT Devices

Definition: IoT (Internet of Things) devices are physical objects embedded with sensors, software, and network connectivity that allow them to collect, exchange, and act on data.

Types of Devices: Include sensors (temperature, humidity, motion), actuators (motors, valves), smart appliances (thermostats, lights), wearable devices (fitness trackers, medical monitors), and industrial IoT devices (machines, robots).

Connectivity: These devices communicate via networks such as Wi‑Fi, Bluetooth, Zigbee, NB‑IoT, LoRaWAN, cellular (4G/5G), or satellite, depending on range, power, and data requirements.

Applications: Found in smart homes, industrial automation, healthcare, agriculture, transportation, energy management, and environmental monitoring.

Data Processing: IoT devices can process data locally (edge computing) or send it to cloud platforms for analytics, visualization, or remote control.

Security & Management: Key considerations include encryption, authentication, firmware updates, and device management to protect against cyber threats and ensure reliable operation
