For Eye Blink sensor :

Here in this tutorial, we will learn everything about Eye Blink Sensor. This sensor is a boon for drivers driving especially in the nighttime. The application of this sensor is huge in today’s era which we are going to discuss at the end of this tutorial.

The sensor has three pins as shown below :
Three pins GND (ground), 5V, OP (output)

The main component of the Eye Blink Sensor is the infrared sensor. The infrared sensor contains two parts. An IR transmitter and an IR receiver. The IR transmitter emits infrared waves onto the eye. While the receiver continuously searches for variations in the reflected waves which indicates that the eye has blinked or not. If the eye is closed then reflected waves will be received by the IR Receiver and the output of the sensor would be low. If the eye is open then all the IR rays will be absorbed by the eye and the output of the eye blink sensor would be high.

Eyeblink Sensor can be used in a variety of applications including robotics and mechatronics projects as it provides excellent results and is very economic to buy.
Eye Blink Sensor is compatible with Arduino, Raspberry Pi, AVR, PIC and almost all other microcontrollers. The IR Variation Across the eye will vary as per eye blink. If the eye is closed output is low otherwise the output is high.

Can you explain about sensitivity? Which side to move, left or right? Plz 🙏🙏🙏

[AniAni-vlnq]

Which resistor is used in this circuit?

[sahilpatil]

minimum distance of range
should given to closed eye or open eye ?

[arignabiswas]

how to control the led of the eye blink sensor .. i want to off the led when my eyes are open ...
