Eye Blink Sensor

The Eye Blink Sensor is a wearable electronic device used to detect eye blinking or eye movement. It works based on infrared (IR) reflection technology or sometimes EEG-based sensing, depending on the model. When the eye is open or closed, the amount of reflected infrared light changes, which is detected by the sensor and converted into an electrical signal.
