Automotive IoT is the ecosystem of physical devices embedded in a vehicle that are equipped with sensors, software, and other technologies for the purpose of connecting to and exchanging data over the internet.

It transforms the car from a standalone machine into a smart, connected asset.

The 'things' in Automotive IoT include a wide range of devices: - **Telematics Control Units (TCUs):** The core communication hub, providing GPS tracking and cellular connectivity.

- **On-Board Diagnostics (OBD) readers:** Devices that plug into the OBD-II port to access vehicle health data and fault codes.

- **Sensors:** A vast array including vibration sensors for predictive maintenance, temperature sensors, fuel level sensors, and tire pressure monitoring systems (TPMS).

- **Cameras and Vision Systems:** AI-powered dashcams that analyze driver behavior and road conditions.

- **Infotainment Systems:** Connected systems that provide navigation, media, and communication.

- **V2X Communication Units:** Devices that enable the vehicle to communicate directly with other vehicles and infrastructure.

Together, this network of objects generates the massive amount of data that powers nearly every advanced feature in a modern vehicle, from fleet management and predictive maintenance to autonomous driving and enhanced safety systems.
