Measure Temperature and humidity using Arduino, project with code

Measuring temperature and humidity has become a very easy thing. We using the Arduino board and the temperature and humidity sensor (DHT), in addition to a Lcd to display the values. It only requires the installation of these components together. As well as programming the Arduino board with the appropriate code to measure the temperature and humidity and display it on the Lcd 16×2.
In this post we will learn how to measure temperature and humidity using Arduino

Electronic components needed :

DHT sensor
16×2 lcd display + I2C
Electrical wires
Arduino UNO
Breadboard

Circuit diagram :

Arduino programming code :

#include <DHT.h>
#include <LiquidCrystal_I2C.h>
//by www.andprof.com
DHT dht(2, DHT11);
LiquidCrystal_I2C lcd(0x27, 16, 2); //0x27 or 0x3F

int temp;
int humidity;

void setup() {
  // put your setup code here, to run once:
dht.begin();
lcd.init();
lcd.backlight();
}

void loop() {
  // put your main code here, to run repeatedly:
delay(2000);
temp = dht.readTemperature();
humidity = dht.readHumidity();

lcd.setCursor(0,0);
lcd.print("Temp: ");
lcd.print(temp);
lcd.print(" C");

lcd.setCursor(0,1);
lcd.print("Humidity: ");
lcd.print(humidity);
lcd.print(" %");
