Key Features of Eye Blink Sensor

Adjustable sensitivity: Onboard potentiometer lets you fine-tune detection threshold to accommodate different users, lighting conditions, and mounting distances.
Dual output modes: Both digital and analog outputs give you flexibility-use digital for simple blink counting or analog for detailed signal analysis and waveform study.
Ultra-compact and lightweight: At under 5 grams, the sensor mounts comfortably on glasses, headbands, or custom wearable frames without causing discomfort.
Wide microcontroller compatibility: Works seamlessly with Arduino, ESP32, ESP8266, Raspberry Pi, and STM32 at both 3.3V and 5V logic levels.
Visual feedback: Onboard LED lights up with each detected blink, making calibration and debugging quick and intuitive.
Low power consumption: Efficient IR sensing draws minimal current, making it suitable for battery-powered wearable and portable applications.

Perfect For

Driver Drowsiness Detection System: Mount the sensor on glasses or a visor to monitor blink rate and duration. When prolonged eye closure or reduced blink frequency is detected, trigger an audible alarm via a buzzer or send an alert to a connected smartphone to prevent accidents caused by drowsy driving.
Blink-Controlled Wheelchair: Build an assistive mobility device for individuals with severe physical disabilities. Map specific blink patterns (single blink for forward, double blink for stop, prolonged closure for turn) to wheelchair motor commands using an Arduino or ESP32, enabling hands-free navigation.
Eye Blink Communication Device: Create a communication aid for patients with locked-in syndrome or ALS. Translate blink sequences into letters, words, or predefined messages displayed on an LCD screen or transmitted via Bluetooth to a caregiver's device.
Fatigue Monitoring for Industrial Workers: Integrate the sensor into safety helmets or headgear worn by machine operators, miners, or factory workers. Log blink patterns to an IoT dashboard and trigger alerts when fatigue indicators are detected, improving workplace safety.
Blink-Controlled Home Automation: Use specific blink patterns to control lights, fans, or appliances through a relay module. Combined with an ESP32 and Wi-Fi, create a completely hands-free smart home interface for accessibility applications.
Gaming and HCI Interface: Integrate blink detection into video games or computer interfaces as an alternative input method. Trigger in-game actions like shooting, jumping, or selecting menu items with deliberate eye blinks for a unique interactive experience.
