Can someone help me how to combine 2 coding for max30100 with Load Cell HX711. I already try but when upload only Load Cell HX711 sensor function.
This program MAX30100
#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();
}
}
This program Load Cell HX711
#include <HX711.h>
HX711 scale(6, 7); //Load Cell DT 6, SCK 7
float calibration_factor = -423; //Load Cell
float units; //Load Cell
float ounces; //Load Cell
void setup ()
{
Serial.begin(9600);
scale.set_scale(calibration_factor);
scale.tare();
}
void loop ()
{
units = scale.get_units(),10;
if (units < 0)
{
units = 0.00;
}
ounces = units * 0.035274;
Serial.print("Berat:");
Serial.print(units);
Serial.println(" g");
}
Please help me....
