ADS-30102-M_Demo

Demo-1

• 集成开发环境：Arduino IDE

• 开发板：DCcduino（它和Arduino UNO开发板是互相兼容的）

  

1. 在Arduino UNO示例SoftwareSerialExample.ino的基础上进行修改，编写一个简单的测试程序

   #include <SoftwareSerial.h>
   SoftwareSerial mySerial(10, 11);  // RX, TX
   char ch;
   void setup() {
     // Open serial communications and wait for port to open:
     Serial.begin(115200);
     while (!Serial) {
       ;  // wait for serial port to connect. Needed for native USB port only
     }
     Serial.println("Hello,I'm DCcduino UNO!");
     // set the data rate for the SoftwareSerial port
     mySerial.begin(9600);
     mySerial.print("STOP\r\n");
     delay(50);
     mySerial.print("START\r\n");
     delay(50);
     //清空串口缓存
     while (mySerial.read() >= 0) {};
   }
   void loop() {
     //获取传感器心率数据
     mySerial.print("HR\r\n");
     while (mySerial.available()) {
       ch = mySerial.read();
       Serial.print(ch);
     }
     delay(50);
     //获取传感器血氧饱和度数据
     mySerial.print("SPO2\r\n");
     while (mySerial.available()) {
       ch = mySerial.read();
       Serial.print(ch);
     }
     delay(50);
     delay(1000);
   }
   

2. 烧录程序后查看串口监视器信息

   

3. 将食指指腹紧贴于传感器模块发出红光的地方，继续观察串口监视器打印出的信息

   

4. 在之后的多次测试过程中，模块一直运行正常，检测速度较快，在几秒种内就能测算出心率血氧数据且数据稳定可靠
