心率血氧检测代码

以下是一个简单的心率和血氧检测的代码示例：

#include <Wire.h>
#include "MAX30105.h"
#include "heartRate.h"

MAX30105 particleSensor;

void setup()
{
  Serial.begin(115200);

  // Initialize sensor
  if (!particleSensor.begin(Wire, I2C_SPEED_FAST)) {
    Serial.println("MAX30105 was not found. Please check wiring/power.");
    while (1);
  }

  // Configure sensor
  particleSensor.setup(0x1F, 4, 2, 411, 4096); // Sensitivity, sample rate, LED brightness, pulse width

  // Set up heart rate calculation
  heartRate.begin();
}

void loop()
{
  // Get raw IR value
  int32_t irValue = particleSensor.getIR();

  // Calculate heart rate and SpO2
  float heartRate = heartRate.getHeartRate();
  float spo2 = heartRate.getSpO2();

  // Print results
  Serial.print("Heart rate: ");
  Serial.print(heartRate);
  Serial.print(" bpm, SpO2: ");
  Serial.print(spo2);
  Serial.println("%");

  // Wait a bit before taking another reading
  delay(1000);
}

这段代码使用 MAX30105 传感器来读取红外光和红光反射数据，并使用心率检测库来计算心率和血氧饱和度。代码中的参数可以根据具体传感器和应用进行调整。注意，该代码仅供参考，实际应用中应根据具体情况进行修改和优化。
