# Arduino DHT11 Library

## 1. Functions and Constants

| Name        | Type      | Intro                                                  |

| ----------- | --------- | ------------------------------------------------------ |

| update()    | Function  | return true if update successfully,else will be false  |

| temperature | Constants | this value will update after calling update() function |

| humidity    | Constants | this value will update after calling update() function |

## 2. Examples

```cpp

#include 

const uint8_t dht11_pin = 2;

DHT11 dht11(dht11_pin);

void setup() {

    Serial.begin(115200);

}

void loop() {

    if (dht11.update()) {

        Serial.print("DHT11 Okay,humidity is ");

        Serial.print(dht11.humidity);

        Serial.print(", temperature is ");

        Serial.println(dht11.temperature);

    } else {

        Serial.println("DHT11 ERROR!");

    }

    delay(2000);

}

```

> Attention:

>

> - According to DHT11 datasheet, intervals between every sensor update should be at least **2 seconds**.
