Arduino Nano Based Anti-Sleep Smart Alarm Using an IR Proximity Sensor

IR Proximity Sensor and Arduino nano are being used in making different types of devices today. There are mainly two types of LEDs in IR sensor, in which one works as IR transmitter and other as IR receiver. IR radiation is mainly absorbed by black objects. Our work is based on a principle that when a person’s eyes are open, the IR radiation is absorbed by the black pupil of the eyes, but when the eyes remain closed for a long time, the IR radiation emitted by the IR transmitter is reflected by the eyelids and absorbed by the IR receiver. The received signals are transmitted to the Arduino nano input pin by the IR Proximity Sensor’s signal pin, due to which output pin of Arduino nano gets activated by uploaded programme. Arduino IDE application is being used to program the Arduino board. The proposed work is cost-effective, easy to implement an innovative idea to enhance driver safety.
