Current Sensors are sensor devices used to detect and measure electric current flowing through a conductor or circuit. They convert the presence or magnitude of current into a corresponding electrical signal that can be monitored, processed, or used for control purposes.

Within the broader Sensors category, current sensors are commonly distinguished by their underlying sensing principles and signal output methods, enabling integration into a wide range of electronic and electrical systems.

• Function: Provide current detection and measurement by translating current-related effects into an output signal.
• Measurement approach: Support both direct and indirect sensing methods depending on the sensing technology.
• System role: Enable current monitoring, feedback, and protection functions at the system level.
