Covid-19 and its variant viruses have killed millions of human population, whereas still more numbers are being infected and admitted every day. As per records, severe infection causes Pneumonia associated with high pulse and breathing rates, and low blood oxygen. Pulse rate and blood oxygen level are two parameters that medical experts use to diagnose and measure Pneumonia and Bronchitis through sensors. Therefore, it has become a very important research direction to detect the pulse wave accurately, quickly, and conveniently. Those sensors are used to scan patients’ measurements which are widely available in developed countries. As their costs are prohibitively high for wide penetration in developing countries we developed and tested the performance of an Atmel ATmega 328P MCU and MAX30100 sensor kit-based pulse rate, blood oxygen monitor, and blood pressure. By using our project we can know whether the person is having danger of cardiac arrest, fever. The parameters here we measured are temperature, heartbeat, and pulse by using respective sensors. The data from the sensors are given to the Arduino Uno. This project aims at developing a system that gives pulse rate and SPO2 respectively. These sensors are interfaced with an Arduino microcontroller board. The value of saturation oxygen level, pulse rate, and blood pressure records will be uploaded to cloud software
