Eye Blink Detection Analog & Digital Sensor with Goggles High Quality

How to Use

• Wear the goggles and align sensor above the eye
• Read analog for blink intensity & waveform
• Read digital for on/off blink detection
• Adjust sensitivity with screwdriver

Analog Blink Detection (Waveform)

void setup() {
  Serial.begin(9600);  // Start serial communication
}

void loop() {
  int sensorValue = analogRead(A0);  // Read analog pin
  Serial.println(sensorValue);       // Print to Serial Plotter
  delay(10);                         // Slight delay for smooth plotting
}

Digital Blink Detection (On/Off Signal)

void setup() {
  Serial.begin(9600);     // Start serial communication
  pinMode(3, INPUT);      // Digital pin D3 as input
}

void loop() {
  int blinkState = digitalRead(3);  // Read digital output
  Serial.println(blinkState);       // 1 = blink detected, 0 = no blink
  delay(100);                       // Delay to avoid flooding the serial
}

1. Upload the code to your Arduino
2. Go to Tools → Serial Monitor
3. Set baud rate to 9600
4. Watch for "1" (blink) and "0" (no blink) in real-time

The Eye Blink Detection Analog & Digital Sensor with Goggles is a powerful tool designed for Arduino enthusiasts, developers, and researchers interested in human-computer interaction and biometric sensing. This ready-to-use module combines an amplified analog signal output and digital threshold detection with a pair of safety goggles to provide a non-intrusive, hands-free solution for tracking eye blinks with precision.

Why Analog Sensor?
Unlike traditional digital-only blink sensors that merely distinguish between open and closed eyes, this advanced analog+digital sensor outputs waveforms. These waveforms allow you to capture full, partial, and quick blinks, as well as unusual eye activity like prolonged open states—making it ideal for more sophisticated projects such as fatigue detection, assistive tech, and research.

Key Features:

• Dual analog and digital signal output

• Noise-canceling and signal amplification circuitry

• No soldering required: Plug & Play with Arduino using color-coded pins

• Adjustable sensitivity via onboard potentiometer

• Comfortable integrated goggle frame with mount

• Easy-to-follow connection diagram included

• Lightweight, adjustable, and reusable

• Detects subtle blink variations (partial blinks, double blinks, long blinks)

Technical Specifications:

• Power Supply: 5V (Compatible with Arduino)

• Output: Analog (A0), Digital (D3)

• Adjustable sensitivity (screwdriver adjustment)

• Indicator LEDs for power and digital output

• Goggle-mounted for fixed eye alignment

How to Use:

1. Wear the goggles and ensure the sensor aligns directly with your eye.

2. Connect the sensor pins (VCC, GND, A0, D3) to your Arduino or compatible development board.

3. Use the analog signal for waveform-based detection or the digital signal for simple blink recognition.

4. Adjust the threshold if needed using the onboard potentiometer.

Applications:

• Eye-controlled interfaces

• Assistive devices for differently-abled users

• Human-computer interaction projects

• Drowsiness/fatigue detection systems

• Robotics and automation

• Educational and research experiments

Package Includes:

• 1 x Eye Blink Analog & Digital Sensor Module

• 1 x Pre-mounted Sensor Frame with Goggles

Why Choose This Product?
Whether you're building an accessibility device, experimenting with biometric feedback, or learning about biosignals, this goggle-integrated blink sensor gives you the flexibility of both analog and digital outputs in one simple, no-soldering-required solution.

Note:

• Not a medical device.

• Not suitable for prolonged wear.

• Ensure the sensor is aligned directly above the eye for accurate readings. Adjust goggle position or sensor as necessary.
