Telemetry
Data collected by the device is called telemetry. This is the eyes-and-ears data that IoT devices provide to applications. Telemetry is read-only data about the environment, usually collected through sensors.

Internet of things

The use of network-connected devices, embedded in the physical environment, to improve some existing process or to enable a new scenario not previously possible.

Challenges

  1. Brownfield deployment (legacy infrastructure) means companies will need to confront the task of integrating new devices and technologies into existing networks.
  2. Security and compliance
  3. IT/OT convergence means enterprise and industrial operations will need to modify and adjust their processes to accommodate IIoT devices and data.
