Adaptive Fingerprint Sensor Switching for Wet Screen Unlocking

The system dynamically switches between semiconductor fingerprint sensor and optical fingerprint sensor based on the detected humidity level. When humidity exceeds the threshold, the system transitions from using the semiconductor sensor to using the optical sensor, making the sensor selection adaptive rather than static. This resolves the contradiction by allowing the system to maintain high unlocking speed through the semiconductor sensor under normal conditions while ensuring stability through the optical sensor when the screen is wet.

The system changes the operational parameter (sensor type) based on the humidity parameter. By monitoring the humidity level and comparing it against a threshold, the system selects the appropriate sensor mode: semiconductor sensor for low humidity conditions or optical sensor for high humidity conditions. This parameter-based switching resolves the contradiction between speed and stability by adapting the sensor selection to environmental conditions.

The system dynamically selects the optical sensor only when necessary (high humidity conditions) rather than using it continuously. This dynamic approach ensures stability when needed while avoiding the speed penalty during normal conditions, as the system switches to the faster semiconductor sensor when humidity is low.

The system changes the sensor selection parameter based on the humidity parameter. When humidity is below the threshold, the semiconductor sensor is selected for faster unlocking; when humidity exceeds the threshold, the optical sensor is selected for stable identification. This conditional parameter change resolves the contradiction between speed and stability.

The system implements multi-functionality by incorporating both semiconductor and optical fingerprint sensors, allowing it to handle multiple scenarios: fast unlocking under normal conditions and stable identification in wet conditions. The dual-sensor design provides universal coverage across different humidity environments, resolving the contradiction between complexity and adaptability.

The humidity detection mechanism acts as an intermediary that mediates between the two sensor types. By detecting the humidity level and triggering the appropriate sensor selection, this intermediary enables the system to adapt to different conditions without requiring complex manual intervention or overly complicated decision-making logic.
