与Bogdan的对话让我意识到修改 Arduino 草图以使用连接到几乎任何 Arduino 设备的独立加速度计 + 陀螺仪传感器非常容易，然后用于CurieGraph.py 可视化数据。鉴于收集地震读数的目的是证明无需复杂或专门的设备就可以大规模众包数据，我在办公桌上翻找“ITG-MTU”/“GY-521”/“ MPU-6050 ”传感器板，并为其编写了以下草图。CurieGraph.py 可能有几次启动失败，但通常在第三次尝试时它会正确启动。
#include
const int MPU_addr=0x68; // I2C address for ITG-MTU
int ax, ay, az, temp, gx, gy, gz;
void setup(){
Serial.begin(9600);
Wire.begin();
Wire.beginTransmission(MPU_addr);
Wire.write(0x6B);
Wire.write(0);
Wire.endTransmission(true);
}
String jsonEncodeValue(String key, float keyVal){
return "\"" + key + "\":" + String(keyVal) + "";
}
String assembleJson(String keysAndVals){
return "{" + keysAndVals + "}";
}
void loop(){
Wire.beginTransmission(MPU_addr);
Wire.write(0x3B);
Wire.endTransmission(false);
Wire.requestFrom(MPU_addr, 14, true);
ax = Wire.read()<<8|Wire.read();
ay = Wire.read()<<8|Wire.read();
az = Wire.read()<<8|Wire.read();
temp = Wire.read()<<8|Wire.read();
gx = Wire.read()<<8|Wire.read();
gy = Wire.read()<<8|Wire.read();
gz = Wire.read()<<8|Wire.read();
// temp = temp/340.00+36.53; // Convert temp data to celsius - NOT BEING USED
String keyVals = jsonEncodeValue("ax", ax) + ",";
keyVals += jsonEncodeValue("ay", ay) + ",";
keyVals += jsonEncodeValue("az", az) + ",";
keyVals += jsonEncodeValue("gx", gx) + ",";
keyVals += jsonEncodeValue("gy", gy) + ",";
keyVals += jsonEncodeValue("gz", gz);
Serial.println(assembleJson(keyVals));
delay(100);
}
