IoT (Internet of Things)
Definition
The category of networked physical objects embedded with sensors, processors, and communication modules that collect and transmit data without continuous human interaction. For forensic purposes, IoT includes wearables, smart-home devices, connected vehicles, and industrial sensors.

Common questions
Why are IoT devices treated as a distinct evidence category?+
Unlike a phone or computer, an IoT device usually has no user interface for direct interrogation, stores only fragments of data locally, and relies on a manufacturer's cloud service for the fuller record, so acquisition often requires a legal request to that service rather than physical examination alone.
What makes IoT data useful for corroborating a timeline?+
Sensors on wearables, smart locks, or thermostats log events automatically and continuously without requiring the user to take any action, which can place a person or activity at a location and time independent of testimony or a device the person could have altered.
