    代码

    ```c

    include “DHT.h”

DHT dht;

void setup() { Serial.begin(9600); dht.setup(2); // data pin 2 delay(1000); }

void loop() { float temperature = dht.getTemperature(); float humidity = dht.getHumidity();

Serial.print(“Temperature is “); Serial.print(temperature, 1); Serial.println(“C”); Serial.print(“Humidity is”); Serial.print(humidity, 1); Serial.println(“%”); delay(3000); } ```
