Detection of any disease of any patient is the only main solution with the help of electronics devices patient can check our heart rate and oxygen level reading. If any problem has not human being then lifestyle has also increased. But if people have any type disease occurred in body then first doctor test and then start the treatment. If people will have any that type of electronics checking device then doctor will not be need to checking the human body problem, then doctor can directly start the treatment basis of device reading.So cardiovascular disease is very dangerous type disease for human being by this human being can be died with in second. This main problem is solved by doctor by treatment if patient reach on time. This work gives a proper system, with the help of that system patient can control our disease by himself that means there is no need of paying extra money for checking heart beat and oxygen level because all reading will have then his treatment directly started no time loss for treatment This research aim is that gives that type idea of idea for designing a device which is useful for normal human. If any device cost is very low and gives a efficient result then any person can take benefit. It design is different other type device, in which Node MCU technology and LCD display and a latest sensor max30100 is used. It will be display on LCD screen, alert by an message which will be sent through mobile phone to the doctor and oxygen level will also display on screen.

Heart pulse sensor, MAX 30100, Nano board, node mcu, Blynk app
