Heart Rate Monitoring System

In this blog post, we’ll delve into the exciting world of heart rate monitoring using Arduino. By combining the power of Arduino microcontrollers with a heart rate sensor, we can create a simple yet effective system to track our heartbeats.

Components You’ll Need:

To build this system, you’ll need the following components:

Arduino Uno: The brain of the system, controlling the sensors and processing data.
Pulse Sensor: Detects the heartbeat through changes in light absorption in your skin.
Jumper wires: for connecting the components.
Breadboard: A platform for building the circuit without soldering.
Resistors: To control the current in the circuit.
LED: Optional, to visually indicate the heartbeats.

Step-by-Step Instructions:
1. Setup the Arduino and Pulse Sensor:
  - Connect the pulse sensor’s VCC to the 5V pin on the Arduino.
  - Connect the GND pin of the pulse sensor to the GND pin on the Arduino.
  - Connect the Signal pin of the pulse sensor to the A0 pin on the Arduino.
2. Build the circuit on the breadboard:
  - Place the Arduino and breadboard side by side.
  - Use jumper wires to connect the components as per the schematic.

Write the Arduino Code:
- Utilize the Pulse Sensor Playground library to read data from the heart rate sensor.
- Process the data to calculate heart rate and display the results on a serial monitor or LCD.

Code Example:

				
					#include <PulseSensorPlayground.h>

PulseSensorPlayground pulseSensor;

void setup() {
  // Initialize the PulseSensor Playground library
  pulseSensor.begin();
}

void loop() {
  int heartRate = pulseSensor.getBeatsPerMinute();
  if (heartRate > 0) {
    Serial.print("Heart Rate: ");
    Serial.print(heartRate);
    Serial.println(" BPM");
  }
}console.log( 'Code is Poetry' );

Tips for Accurate Readings:

Ensure a good connection between the heart rate sensor and your finger.
Avoid excessive movement or pressure on the sensor.
Experiment with different resistor values to optimize sensitivity.

Additional Features:

Visualize Heart Rate: Use an LED or LCD to display the heart rate in real-time.
Store Data: Log heart rate data to a file or send it to a remote server.
Integrate with Other Sensors: Combine heart rate data with other physiological measurements (e.g., temperature, oxygen saturation).

Conclusion

By following these steps and leveraging the capabilities of Arduino, you can create a functional heart rate monitoring system. This project is a great starting point for exploring the world of wearable technology and healthcare applications.
