Please Follow the following code may work out for you.

 

#include <Wire.h>
#include "MAX30100_PulseOximeter.h"
 
#define REPORTING_PERIOD_MS 1000
 
// PulseOximeter is the higher level interface to the sensor
// it offers:
// * beat detection reporting
// * heart rate calculation
// * SpO2 (oxidation level) calculation
PulseOximeter pox;
 
uint32_t tsLastReport = 0;
 
// Callback (registered below) fired when a pulse is detected
void onBeatDetected()
{
Serial.println("Beat!");
}
 
void setup()
{
Serial.begin(115200);
 
Serial.print("Initializing pulse oximeter..");
 
// Initialize the PulseOximeter instance
// Failures are generally due to an improper I2C wiring, missing power supply
// or wrong target chip
if (!pox.begin()) {
Serial.println("FAILED");
for(;;);
} else {
Serial.println("SUCCESS");
}
 
// The default current for the IR LED is 50mA and it could be changed
// by uncommenting the following line. Check MAX30100_Registers.h for all the
// available options.
// pox.setIRLedCurrent(MAX30100_LED_CURR_7_6MA);
 
// Register a callback for the beat detection
pox.setOnBeatDetectedCallback(onBeatDetected);
}
 
void loop()
{
// Make sure to call update as fast as possible
pox.update();
 
// Asynchronously dump heart rate and oxidation levels to the serial
// For both, a value of 0 means "invalid"
if (millis() - tsLastReport > REPORTING_PERIOD_MS) {
Serial.print("Heart rate:");
Serial.print(pox.getHeartRate());
Serial.print("bpm / SpO2:");
Serial.print(pox.getSpO2());
Serial.println("%");
 
tsLastReport = millis();
}
}

Hey Jepoy, please refer the link attached.Modify the code for ESP32 and this will work.
