MAX30102是一种集成了红外发光二极管、可见光发光二极管和光电二极管的传感器,可以实现非侵入式的心率和血氧测量。
以下是一个基于Arduino平台的示例程序,用于从MAX30102传感器读取心率和血氧值:
```c++
#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 not found. Check wiring!");
while (1);
}
// Setup sensor
particleSensor.setup(0x1F, 4, 2, 411, 4096); // Configure sensor with custom settings
// Set LED brightness
particleSensor.setPulseAmplitudeRed(0x0A);
particleSensor.setPulseAmplitudeGreen(0);
}
void loop()
{
// Read sensor data
int32_t irValue = particleSensor.getIR();
int32_t redValue = particleSensor.getRed();
// Calculate heart rate and SpO2
float heartRate = getHeartRate(irValue, redValue);
int8_t spO2 = getSpO2(irValue, redValue);
// Print results
Serial.print("Heart rate: ");
Serial.print(heartRate);
Serial.print(" bpm");
Serial.print(" - SpO2: ");
Serial.print(spO2);
Serial.println("%");
// Wait for 1 second
delay(1000);
}
```
需要注意的是,由于MAX30102是一种光学传感器,因此其测量结果可能会受到外界光线和其他干扰因素的影响,因此在实际使用时需要对传感器进行校准和优化。
