Telemetry data refers to the collection of measurements or other data at remote or inaccessible points and their automatic transmission to receiving equipment for monitoring. In the context of IoT, telemetry data is primarily produced by sensors that monitor conditions in the environment, equipment, or systems.
The correct choice is outputs from sensors because telemetry data typically consists of real-time readings that various sensors capture. This data could include temperature, humidity, pressure, or other specific metrics depending on the application. These outputs are essential for analyzing conditions, making decisions, or performing actions based on the data collected.
Other options, while related to the broader concept of IoT, do not accurately define telemetry data. For example, input from environment sensors describes the role of sensors but does not specify that these inputs are processed and transmitted as telemetry data. Instruction signals denote commands sent to devices rather than measurements collected as telemetry. Lastly, historical data logs refer to recorded data over time, which is based on previously transmitted telemetry but is not the raw data output itself. Therefore, outputs from sensors precisely capture the essence of telemetry in an IoT environment.
