Sensors are electronic components that detect physical, chemical, or environmental conditions and convert them into electrical signals that can be measured, processed, or monitored by electronic systems.

This category broadly covers devices designed to sense changes in a target quantity and provide a corresponding output suitable for interfacing with control, measurement, or signal-processing circuits.

• Function: Convert real-world stimuli into electrical information.
• Scope: Includes a wide range of sensing technologies and signal output methods.
• Integration: May be used as standalone sensing elements or combined with supporting circuitry for signal conditioning and interfacing.
