A defective sensor appears to not change its state. Use this Hotfix to prevent the software from stopping completely

int i = 0;
while (dataAvailable(fd) == 0){
	if(i < TIMEOUT_COUNTER){
		printf("Measurement at sensor timeout do not trust that received data is new");
break;
	}
	delay(POLLING_DELAY); //Potential TODO: avoid this to get faster nearly parralel mesurments
	i++;
}

Attantion dataAvailable is a register on the sensor that indicates that the measurement is finished and ready to be read from the sensor.
Not waiting for this may result in old data being read.
