Commonly employed in driver drowsiness systems, assistive communication devices, and creative Arduino projects, this module provides a digital output that goes HIGH when the eye is closed and LOW when open. The adjustable goggles ensure a stable and consistent fit, making it easy to capture reliable blink signals even in environments with ambient light variation.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensor Type\u003c\/td\u003e\n\u003ctd\u003eIR Emitter \u0026amp; Photodiode\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDetection Method\u003c\/td\u003e\n\u003ctd\u003eReflective infrared\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Signal\u003c\/td\u003e\n\u003ctd\u003eDigital (HIGH when eye closed, LOW when open)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3V – 5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eResponse Time\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;100 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensitivity Adjustment\u003c\/td\u003e\n\u003ctd\u003eOnboard potentiometer\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eGoggles Type\u003c\/td\u003e\n\u003ctd\u003eAdjustable, fits most head sizes\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eDriver Drowsiness Alert System – Trigger an alarm when no blinks are detected for a set period, helping prevent accidents.\u003c\/li\u003e\n  \u003cli\u003eAssistive Communication Switch – Allow individuals with motor impairments to control devices via intentional blinks.\u003c\/li\u003e\n  \u003cli\u003eInteractive Art Installation – Use blink patterns to change lighting, sound, or visuals in a creative display.\u003c\/li\u003e\n  \u003cli\u003eBlink-Based Game Controller – Integrate with Arduino to replace button presses with eye blinks in simple games.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eCompatible with 3.3V and 5V microcontroller boards like Arduino Uno, Nano, ESP32, and Raspberry Pi (with voltage level shifting).
