DHT.h Library not being imported I am trying to read the humidity and temperature using a DHT11 temperature sensor for an Arduino UNO using the DHT.h library. I have my code below:

#include &lt;DHT.h&gt;
#define dataPin 4
dht DHT;

void setup() {
  Serial.begin(9600)

}

void loop() {
  int readData = DHT.read11(dataPin);
  float t = DHT.temperature;
  float h = DHT.humidity;
  Serial.println("Temperature: ")
  Serial.print(t)
  Serial.print(" ºC")
  Serial.println("Humidity: ")
  Serial.print(h)
  Serial.print(" % ")
  delay(2000)
}


When compiling the program, it gives me an error: 

fatal error: DHT.h: No such file or directory


I have also tried with lower case letters, but it will not work. Is there any reason why? Do I have to install it? I have tried to search for the library in the Arduino app Sketch - Include Library - Manage Libraries, but the library is not there.
Download https://github.com/RobTillaart/Arduino/archive/master.zip
Copy the Arduino-master/libraries/DHTstable subfolder of the downloaded file to the libraries subfolder of your sketchbook folder. You can find the location of your sketchbook folder at File > Preferences > Sketchbook location in the Arduino IDE.
Change the first line of your sketch from:

#include &lt;DHT.h&gt;


to:

#include &lt;dht.h&gt;



Now when you try to compile the sketch you will still encounter many errors. However, these are caused by a paucity of semicolons, not by the DHT library, and thus off-topic for this question.
