interfacing Ultrasonic distance sensor with arduino

[kodi.sudar]

hi i am using ultrasonic distance sensor from sunrom
**broken link removed**
i tried interfacing with Arduino uno serially but when i monitor the sensor data in serial monitor window i dont find any data in that , here is my code

char sensorData[10];
int index = 0;
void setup()
{
  Serial.begin(9600);
}
void loop()
{
   // While there is data, and we have read less than 9 characters
   while(Serial.available() > 0 && index < 9)
   {
      char inChar = Serial.read(); // Read a character
      sensorData[index] = inChar; // Store it
      index++;
      sensorData[index] = '\0'; // Null terminate the string
   }

  // Serial.print("Sensor data: ");
   Serial.println(sensorData);

   // Do whatever else you need to do to parse the string and use the data

   index = 0;
}

can any body help me sort out the problem

Post the circuit you have used that is connection of sensor to Arduino board.

Try with modified code
char sensorData[10];
int index = 0;
void setup()
{
Serial.begin(9600);
}
void loop()
{
// While there is data, and we have read less than 9 characters
while(index < 9)
{
if(Serial.available())
{
char inChar = Serial.read(); // Read a character
sensorData[index] = inChar; // Store it
index++;
sensorData[index] = '\0'; // Null terminate the string
}
}

// Serial.print("Sensor data: ");
Serial.println(sensorData);

// Do whatever else you need to do to parse the string and use the data

index = 0;
}

the fails to work, it is not displaying any thing in the serial window.

the circuit is not a big one, i have connected the sensor output ( serial, 9600 baud rate) to the Rx pin (pin 1) in arduino board, 5v supply and ground
