I can't even get past first base with this, what's this error and why?  
I done everything right and included the sensor info into the library, but it's not happening when I verify it.

` fatal error: Adafruit_Sensor.h: No such file or directory`So, where did you put it?

> I done everything right

The compiler doesn't agree with your opinion.

```cpp

```

Looks like the library is not installed or is installed incorrectly

Thanks for looking at my error guys, I used the ADD .Zip Library, anyway I will have to look at it a little closer. So frustrating for a NOOby. Cheers...Gary

If you go into Sketch/Include Library can you see it ?

If not then it is not properly installed

What about Adafruit\_Sensor.h ?

Instead of putting the include \<Adafruit\_Sensor.h\> put #include "DHT.h" or #include \<DHT.h\>  
That should work fine

Of course, it would help if the OP had [read this before posting a programming question](http://forum.arduino.cc/index.php?topic=97455.0) and followed the advice contained in it
