Story

Aim:

Design a health monitoring system which can measure the ECG. The user has to enter the data on a mobile phone and then start taking the test. The data will be send from hardware to mobile phone application via bluetooth. The mobile phone will send the information on the cloud so that the health condition of the patient can be tracked by the doctor.

Working:

The functioning of the device starts from the MSP430G2 launch pad after it receives the analog values from ECG sensor. The received data is sent to mobile application via bluetooth where it is plotted over the graph using ubidots IoT platform. Then the data is send to cloud for analysis where received data is compared with previous data sets and predictions are made using various machine learning algorithms.

About ECG Monitoring:

ECG records the electrical activity generated by heart muscles depolarization, which propagates in pulsating electrical waves towards the skin. Although the electricity amount is in fact very small, it can be picked up reliably with ECG electrodes attached to the skin.

Application:

Electrocardiogram(ECG) is used to access the heart rate and rhyme. This test can often detect heart disease, heart attack, an enlarged heart, or abnormal heart rhythms that may cause heart failure. Now using this device we can easily view and analyse ECG on app and web server whenever we want. We can also track our heart health and predict future diseases.

ecg monitoring code

void setup() {
  // initialize the serial communication:
  Serial.begin(9600);
  pinMode(9, INPUT); // Setup for leads off detection LO +
  pinMode(10, INPUT); // Setup for leads off detection LO -

}

void loop() {
  
  if((digitalRead(9) == 1)||(digitalRead(10) == 1)){
    Serial.println('!');
  }
  else{
    // send the value of analog input 0:
      Serial.println(analogRead(A0));
  }
  //Wait for a bit to keep serial data from saturating
  delay(1);
}
