A sensor plays a crucial role in a data acquisition system by converting physical phenomena into measurable signals. This involves detecting changes in various environmental parameters, such as temperature, pressure, or humidity, and transforming these changes into electrical signals or other types of signals that can be easily interpreted by the system. The ability to accurately convert physical measurements into signals is fundamental for monitoring and controlling processes, enabling data acquisition systems to provide meaningful information for analysis and decision-making.

In contrast, the other options describe different functions that are not the primary role of a sensor. Controlling the environment for measurements pertains more to actuators or controllers, while storing data is the function of data storage systems, and displaying data pertains to user interface components. The primary function of a sensor is its capability to sense and convert physical phenomena, making it an essential component of any effective data acquisition system.
