ESP8266 Heart Rate Sensor Project

This project demonstrates how to interface a heart rate sensor with an ESP8266 microcontroller. It reads and displays the analog output from the heart rate sensor on the Serial Monitor.

Components Needed

Circuit Diagram

Circuit Setup

1.Connecting the Heart Rate Sensor to ESP8266:

Analog Output (Signal) Pin: Connect to an analog pin on ESP8266 (e.g., A0).

vcc: Connect to 3.3V or 5V pin on ESP8266.

gnd: Connect to GND pin on ESP8266.

Instructions

1.Setup:

Upload the provided Arduino code to the ESP8266 using the Arduino IDE.

Open the Serial Monitor to view the analog readings from the heart rate sensor.

2.Testing:

After uploading the code, ensure the heart rate sensor is properly placed and connected.

Observe the Serial Monitor to see the analog values representing the heart rate sensor output.

Applications

Health Monitoring: Use for monitoring heart rate in wearable devices or health monitoring systems.

Fitness Tracking: Integrate into fitness devices for real-time heart rate monitoring during workouts.

Biometric Systems: Incorporate into biometric systems for user authentication based on heart rate variability.

Notes

Sensor Placement: Ensure proper placement of the heart rate sensor on the body for accurate readings.

Power Supply: Ensure stable power supply to the ESP8266 and the heart rate sensor for reliable operation.

calibration: Calibrate the sensor if necessary to match the expected range of heart rate values.
