A data logger can record live sensor values.

A data logger can record live sensor values.

• A. It depends
• B. True
• C. False
• D. Not applicable

Answer: (B)

Data loggers are built to capture measurements from sensors over time by sampling at set intervals and storing the readings. Because of this, they record live sensor values as data is produced, which lets you see how measurements change in real time or near real time and analyze trends later. Some devices can also store pre-recorded data or replay it, but their primary purpose is to log measurements from sensors as they happen. That’s why the statement is true, and the other options don’t fit: they would incorrectly imply that logging live data isn’t guaranteed, or that the concept doesn’t apply.
