Heart Rate Sensor

The Heart Rate Sensor project demonstrates how to use an Arduino Nano to read and display data from a heart rate sensor. This project is ideal for applications in health monitoring, fitness tracking, and educational purposes.

Components Needed

• Arduino Nano
• Heart Rate Sensor
• Breadboard and Jumper Wires

Circuit Diagram

Circuit Setup

1.Connect Heart Rate Sensor to Arduino Nano:

Connect the Vcc pin of the heart rate sensor to the 5V pin on the Arduino Nano.

Connect the GND pin of the heart rate sensor to the GND pin on the Arduino Nano.

Connect the output pin of the heart rate sensor to analog pin A0 on the Arduino Nano.

Instructions

1.Circuit Setup:

Wire the heart rate sensor to the Arduino Nano as described in the circuit setup section.

2.Code Upload:

Connect the Arduino Nano to your computer using a USB cable.

Open the Arduino IDE and paste the provided code.

Select the appropriate board (Arduino Nano) and port from the Tools menu.

Upload the code to the Arduino Nano.

3.Testing:

Once the code is uploaded, place the heart rate sensor on your fingertip or earlobe.

Observe the sensor values printed on the Serial Monitor.

Applications

Health Monitoring: Measure and monitor heart rate for health purposes.

Fitness Tracking: Use heart rate data to track exercise intensity and performance.

Educational Purposes: Demonstrate how biosensors work and how to interface them with microcontrollers.

Notes

Ensure the correct orientation and connection of the heart rate sensor to prevent damage.

Experiment with different placements of the sensor for optimal readings.

The sensor value can be further processed to calculate the actual heart rate in beats per minute (BPM).
