Nowadays, there is a growth in the number of cardiac disorders, including an increased risk of a heart attack. Our suggested solution makes use of sensors that enable heartbeat sensing to identify a person's heart rate even if they are at home. The sensor is then connected to a microcontroller, which allows heart rate values to be checked and transmitted via the internet. The user can specify the maximum and minimum heart rate limits. After these settings are set, the system begins monitoring, and if the patient's heart rate exceeds a particular threshold, the system sends an alert to the controller, which then communicates this over the internet and alerts doctors and concerned users. The technology also warns when a heartbeat is too low. The technology displays the patient's live heart rate whenever the user signs in for monitoring. As a result, those who are concerned can keep an eye on the patient's heart rate and instantly alert them to a heart attack from anywhere, saving the patient's life.
