What is the primary purpose of telemetry in IoT devices?

The primary purpose of telemetry in IoT devices is to send environmental data to the backend. Telemetry involves the automatic transmission of data from remote or inaccessible sources to receiving equipment for monitoring and analysis. In the context of IoT, this typically includes sending various types of data such as temperature, humidity, motion, and other environmental factors back to a central system where it can be processed, analyzed, and acted upon.

This capability is crucial for real-time monitoring and data-driven decision-making. By continuously collecting and transmitting this data, organizations can gain insights into their operations, optimize performance, enhance efficiency, and even predict failures before they occur, which can significantly reduce downtime and maintenance costs.

The other options, while related to the functionality of IoT devices, focus on different aspects. Managing power consumption, updating device configuration settings, and preparing firmware updates are important operational features, but they do not capture the essence of telemetry as primarily focused on data transmission from the device to be utilized for analysis and decision-making.
