Changing I2C Address of Sensors

The I2C address is not 0xC0.
Can you run a I2C Scanner sketch ? It should be 0x60.
There are a few more things in the datasheet that are misleading or incomplete.
When data is read via the I2C bus, I think a repeated start should be used.

Could you try this:

Wire.beginTransmission( 0x60);
int error = Wire.endTransmission();
if( error != 0)
{
  Serial.println( "The sensor is not at 0x60");
}
else
{
  Serial.println( "The sensor is found, changing I2C address");
  Wire.beginTransmission( 0x60);
  Wire.write( 0x53);  // password register
  Wire.write( 0xAA);  // password
  Wire.endTransmission();

  delay(10);    // not described somewhere, just for safety

  Wire.beginTransmission( 0x60);
  Wire.write( 0x00);  // I2C address register
  Wire.write( 0x50);  // new I2C address
  Wire.endTransmission();
}

Then turn off the power and turn on the power. Run a I2C Scanner sketch and check if the new I2C address is found.
