EYE BLINK SENSOR

Rs 696.20 Add


The eye-blink sensor works by illuminating the eye and eyelid area with infrared light, then monitoring the changes in the reflected light using a phototransistor and differentiator circuit. The exact functionality depends greatly on the positioning and aiming of the emitter and detector with respect to the eye.

U
SING SENSOR

Connect regulated DC power supply of 5 Volts. Black wire is Ground, Next middle wire is Brown which is output and Red wire is positive supply. These wires are also marked on PCB.To test sensor you only need power the sensor by connect two wires +5V and GND. You can leave the output wire as it is. When Eye closed,
LED is off & the output is at 0V.Put Eye blink sensor glass on the face within 15mm distance, and you can view the LED blinking on each Eye blink.The output is active high for Eye close and can be given directly to microcontroller for interfacing applications.
EYE BLINK OUTPUT

5V (High)    →   LED ON When Eye is close.

0V (Low)   →   LED OFF when Eye is open.
