代码编写

安装DHT11库

#include <DHT.h>
DHT dht(8,DHT11);
void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  dht.begin();
}
void loop() {
  // put your main code here, to run repeatedly:
  delay(2000);
  Serial.println();
  Serial.print(" 温度是 ： ");
  Serial.println(dht.readTemperature());
  Serial.print(" 湿度是 ： ");
  Serial.println(dht.readHumidity());
}
