What does the term "sensor" specifically refer to in the context of a control system?

In the context of a control system, the term "sensor" specifically refers to a device that converts input into signals. Sensors are designed to detect physical phenomena such as temperature, pressure, light, motion, or other environmental conditions and convert this information into a format that can be interpreted by a control system. This is crucial for the system to process data and make informed decisions based on real-world inputs.

For instance, a temperature sensor will take the ambient temperature and produce an electrical signal that corresponds to that temperature, allowing the control system to assess conditions and make necessary adjustments accordingly. By converting physical inputs into readable signals, sensors play a foundational role in monitoring and controlling various processes in automation and control systems.
