What is a science data log?

An organised record of observations, measurements, or experimental conditions gathered over time is called a science data log, or just a data log. These days, it's more often used to describe data that is automatically recorded and saved by electronic devices known as data loggers, though it can also refer to a physical notebook where researchers manually record entries.

Certain parameters, such as temperature, pressure, humidity, light, or pH, are continuously monitored and recorded by these sensor-equipped devices. Scientists can track trends, spot anomalies, and learn from experiments or environmental monitoring by analysing the data, which is internally stored and can subsequently be transferred to a computer.
