Hello,  
i want to messure a temperature and use SHT75 from Sensirion. I have a board Arduino Uno. I could find some codes for this sensor, but if i use a serial monitor i just see -40. I use a digital Pin2 as a DataPin and 13 as a ClockPin and this code [How to communicate text and numbers over serial - Troubleshooting - Arduino Forum](http://forum.arduino.cc/index.php?topic=49669.0;wap2); The question is if this sensor compatible with Arduino ( I2C) communication?

Thank you

Do you use

```cpp
#include <Sensirion.h>

```

in your code?  
I did not see that in your example code..

I got this error message :  
\Arduino\hardware\arduino\cores\arduino/WString.h:116: error: declaration of C function 'StringSumHelper& operator+(const StringSumHelper&, const char\*)' conflicts with  
\Arduino\hardware\arduino\cores\arduino/WString.h:115: error: previous declaration 'StringSumHelper& operator+(const StringSumHelper&, const String&)' here

and a lot of ohter errors if i ad this library.
