PULSE SENSOR USING ARDUINO

Abstract

ABSTRACT This project focuses on developing a pulse sensor using an Arduino microcontroller, aimed at creating a low-cost, accurate device for heart rate monitoring. The system employs a photoplethysmographic (PPG) sensor to measure variations in blood volume by detecting the light reflected from the skin's surface. The Arduino processes these light signals to calculate the pulse rate in real time. The design includes a display module, such as an LCD, to show the heart rate, or it can interface with a computer for data logging and analysis. The sensor's simplicity, affordability, and ease of calibration make it an ideal tool for both educational applications and personal health tracking. This project highlights the effectiveness of integrating open-source hardware with basic physiological sensors to provide valuable health metrics. Key benefits include the ability to monitor heart rate continuously, adaptability to various display options, and potential for fmther customization and enhancement. The implementation of this pulse sensor demonstrates a practical approach to wearable health technology using readily available components.

THE FIELD OF INVENTION (MEDICAL INDUSTRY)
The invention pe1tains to innovative advancements in the Medical, and biomedical industries,
specifically in the areas of medical, pulse checking and Arduino board
BACKGROUND OF THE INVENTION
The development of pulse sensors has become increasingly significant with the rise of wearable
health technology. Traditional methods of heart rate monitoring often required expensive and bulky

works by detecting changes in blood volume through light absorption and reflection in the skin.
This method, though simple, provides valuable data on heart rate and circulatory health. Prior to
this, similar devices were typically expensive and complex, making them less accessible for
educational and personal health applications. Arduino, an open-source electronics platform, offers
a versatile and user-friendly envirumuent for integrating sensors and processing data. Its
widespread availability and supportive community have facilitated the development of numerous
DIY health monitoring projects. By leveraging Arduino's capabilities, this pulse sensor project
aims to provide an accessible solution for real-time heart rate monitoring. This invention builds
upon the advancements in sensor technology and microcontroller applications, making heart rate
monitoring more affordable and adaptable. The combination of PPG sensors with Arduino's
processing power creates a practical tool for both educational purposes and everyday health
tracking.
