librerie problem

i have this code to DHT11 sensor
but to compile generate this error:

Arduino: 1.6.12 (Windows 10), Board: "Arduino/Genuino Uno"

In file included from C:\Users\javier\Documents\Arduino\sensor1\sensor1.ino:1:0:

C:\Users\jack\Documents\Arduino\libraries\DHT/DHT_U.h:25:29: fatal error: Adafruit_Sensor.h: No such file or directory

#include <Adafruit_Sensor.h>

^

compilation terminated.

exit status 1
Error compiling for board Arduino/Genuino Uno.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

how to solve it?
somebody could help me?

That suggests one of two things. Either you have the name wrong or you have not installed the library you want to reference.

...R

thanks for your help...

I had installed the library correctly, but for some reason I did not install the file

#include <Adafruit_Sensor.h>
I had to copy it manually

I had installed the library correctly, but for some reason I did not install the file

Then you did NOT install the "librerie" correctly!

Hello Friends,
I have found out the solution to this problem. Just download the adafruit common sensor driving library from here:-

https://github.com/adafruit/Adafruit_Sensor

After downloading, just install it and it should work fine...
