Eye Blink Sensor

Eye Blink Sensor Module

The eye blink sensor module is a non-invasive device designed to detect eye blinks using infrared (IR) technology. It measures changes in reflected IR light caused by eyelid movement, making it ideal for human-machine interaction and assistive technology applications.

Key Features

• IR-Based Detection: Uses infrared light to detect eye lid movement
• Non-Contact Sensing: Safe and comfortable to use
• Analog Output: Provides signal variations based on blink activity
• High Sensitivity: Detects even slight eye movements
• Compact Design: Easy to integrate into wearable or embedded systems
• Low Power Consumption: Suitable for portable devices

Applications

• Assistive Technology: Communication for physically challenged users
• Human-Computer Interaction: Control systems using eye gestures
• Medical Monitoring: Eye activity and fatigue detection
• Wearable Devices: Smart glasses and head-mounted systems
• DIY Electronics: Experimental and research projects

Technical Specifications

• Operating Voltage: 3.3V–5V
• Output Type: Analog (some modules may include digital output)
• Detection Method: Infrared reflection
• Interface: ADC / GPIO compatible
• Sensing Distance: Short range (near-eye placement required)
• Operating Temperature: Typically 0°C to 50°C
