Eye Blink Sensor with Goggles – Detect Blinks for Safety & Control
Eye Blink Sensor with Goggles – Compact IR Blink Detection Module
The Eye Blink Sensor with Goggles uses an infrared emitter and photodiode to detect eye blinks. 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.

What You Can Build With This
- Driver Drowsiness Alert System – Trigger an alarm when no blinks are detected for a set period, helping prevent accidents.
- Assistive Communication Switch – Allow individuals with motor impairments to control devices via intentional blinks.
- Interactive Art Installation – Use blink patterns to change lighting, sound, or visuals in a creative display.
- Blink-Based Game Controller – Integrate with Arduino to replace button presses with eye blinks in simple games.
Compatibility
Compatible with 3.3V and 5V microcontroller boards like Arduino Uno, Nano, ESP32, and Raspberry Pi (with voltage level shifting). The digital output connects directly to any GPIO pin. Low current draw makes it ideal for battery-powered and wearable projects.
Wiring Notes
Connect VCC to 5V (or 3.3V), GND to ground, and OUT to a digital input pin. Adjust the onboard potentiometer to set the blink detection threshold according to ambient light and eye characteristics.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, it works directly with Arduino Uno. Connect VCC to 5V, GND to GND, and OUT to any digital pin for a clean HIGH/LOW signal.
How do I adjust the sensitivity?
Turn the onboard potentiometer clockwise to increase sensitivity (detects weaker blinks) and counterclockwise to reduce it, which is useful in bright ambient light or for users with eyelash shadows.
Can I use it without the goggles?
You can mount the sensor on any glasses frame or holder, but the included adjustable goggles provide optimal sensor-eye alignment and reduce external light interference for consistent detection.
