好的,以下是一份基本的Arduino代码,可以使用ESP8266模块和MAX30100血氧传感器,实现血氧浓度检测:
```C++
#include <Wire.h>
#include "MAX30100_PulseOximeter.h"
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
// Replace with your network credentials
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
ESP8266WebServer server(80);
#define REPORTING_PERIOD_MS 1000
PulseOximeter pox;
uint32_t tsLastReport = 0;
WiFiServer wifiServer(80);
void handleRoot() {
server.send(200, "text/plain", "Hello from ESP8266!");
}
void setup() {
Serial.begin(115200);
WiFi.begin(ssid, password);
Serial.println("");
// Wait for connection
while (WiFi.status() != WL_CONNECTED) {
delay(1000);
Serial.print(".");
}
Serial.println("");
Serial.print("Connected to ");
Serial.println(ssid);
Serial.print("IP address: ");
Serial.println(WiFi.localIP());
// Initialize the PulseOximeter instance
pox.begin();
// Make sure to call update as fast as possible
pox.setOnBeatDetectedCallback(onBeatDetected);
}
void loop() {
server.handleClient();
// Update the PulseOximeter instance
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();
}
}
void onBeatDetected() {
Serial.println("Beat Detected!");
}
```
请注意,这只是一个基本的代码示例,需要进行修改以适应您的具体硬件和网络设置。另外,为了使该代码工作,您还需要在ESP8266上安装MAX30100库和ESP8266WiFi库。
