Sketch -> Include Library -> Manage Libraries -> DHT sensor library -> Install

Arduino IDE:

#include<DHT.h>

#define DHTPin 2

#define DHTType DHT11

DHT dht(DHTPin, DHTType);

// DHT dht(D2, 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:

float h = dht.readHumidity();

float t = dht.readTemperature();

Serial.println();

Serial.print("Do am:");

Serial.println(h);

Serial.print("Nhiet do:");

Serial.println(t);

delay(1000);
