Heart Beat Pulse Checking Through Arduino Mega

Introduction:

• In this article I explain about Heart Beat Pulse checking through the Arduio Mega. It can easily display the wave on a PC monitor.
• In the PC monitor it displays the reading of the pulse.
• The wave form can be displayed in the sine wave form. 

Parts Of List: 

• Arduino Mega
• Easy pulsev1.1 sensor 
• HRM-2511E
• Hookup wires 
• PC.

Connection:

Step 1: Connection from the Easy pulsev1.1 sensor to Arduinomega.


Figure1: Easy pulsev1.1 

• Connect the Vcc in the Easy pulse v1.1 sensor to the Vcc of the Arduino Mega.  
• Connect the Gnd in the Easy pulse v1.1 sensor to the Gnd of the Arduino Mega.
• Connect the Ao in the Easy pulse v1.1 sensor to the Ao of the Arduino Mega.

Figure2: connection of HRM-2511E to Easy pulsev1.1

Connect the HRM-2511E and Easy pulsev1.1 in the powercable.

 

Programming

void setup()
 {
Serial.begin(115200);
}

void loop()
{
  int sensorValue = analogRead(A0);
  Serial.println(sensorValue);
  delay_x(5);
}

void delay_x(uint32_t millis_delay)
{
  uint16_t micros_now = (uint16_t)micros();

  while (millis_delay > 0)
{
  if (((uint16_t)micros() - micros_now) >= 1000)
 {
  millis_delay--;
  micros_now += 1000;
    }
  }
}

Explanation:

• It can easily checkthe heart pulse in the body.
• Connect to the HRM-2511E and see the heart beat pulse in the PC monitor.
• It will display with the sine wave pulse as the correct wave form.
