Today, the number of heart diseases is increasing, including an increased risk of heart attack. In the proposed system, by using a sensor, you can detect your heart rate using heart rate detection even at home. Next, connect the sensor to your microcontroller so that it can check your heart rate readings and send them over the internet. Users can set both upper and lower heart rate limits. After setting these limits, the system will start monitoring and as soon as the patient's heart rate exceeds the specified limits, the system will send an alert to the controller. The controller broadcasts it over the internet to alert doctors and affected users. The system will also warn you of a low heart rate. The system also displays the patient's live heart rate whenever the user logs in for monitoring. In this way, people can monitor their heart rate and instantly send a heart attack warning to a patient from anywhere so that the person can be rescued in time.
