What is the primary function of sensors in CPS nodes?

The primary function of sensors in Cyber-Physical Systems (CPS) nodes is to collect data from the environment. Sensors serve as the vital interface between the physical world and the cyber systems by measuring various physical phenomena, such as temperature, pressure, motion, light, and more. This data gathering is essential for the operation of CPS, as it allows the system to monitor its surroundings and make informed decisions based on real-time information.

The collected data is often used to improve system performance, enhance automation, and facilitate responsive actions in reaction to environmental changes. This role is fundamental in enabling CPS to achieve their goals of optimizing processes, improving safety, and enhancing user experience by providing accurate and timely insights into the physical state of systems and environments.

In contrast, performing actions based on data, controlling power supply, and storing data and programs are functions that relate more to other nodes or components within the CPS architecture. While those roles are important, they do not define the primary purpose of sensors, which is specifically focused on data collection.
