Eye Blink Sensor

An eye blink sensor relies on infrared technology to detect if a person's eye is closed. The sensor is made up of two components: an infrared transmitter and an infrared receiver. The transmitter emits infrared waves onto the eye, while the receiver searches for changes in the reflected waves, indicating that the eye has blinked. The sensor's output is sent to a microcontroller board, such as Arduino, Raspberry Pi, AVR, PIC, or other microcontrollers.

To create an eye blink sensor with an Arduino, one requires an eye blink sensor, an Arduino board, and a switch between the power supply and the Arduino. The sensor has three pins: GND (ground), 5V, and OP (output). The sensor's output is transmitted to the Arduino board, which can be programmed to execute various tasks based on the output.

Note: This eye blink sensor is strictly restricted for hobby projects and not recommended for real-time use.

1. What is the working principle of an eye blink sensor? 

  • The eye blink sensor illuminates the eye with infrared light and monitors the changes in the reflected light. The results are calculated using infrared light reflected from the eye. The sensor output is active high for Eye close and can be given directly to the microcontroller for interfacing application 

2. What is an Eye Blink Sensor? 

  • This Eye Blink sensor senses the eye blink using infrared. The Variation Across the eye will vary as per eye blink. If the eye is closed the output is high otherwise the output is low.

3. Where can I use the Eye Blink Sensor? 

  • It can be used as Digital Eye Blink Monitor, Vehicle Accident Prevention, Suite for real-time driving applications, and Facility to interface microcontroller devices
