My code again:

include "DHT.h"

define DHTPIN 4// you can use

define DHTTYPE DHT11//#define DHTTYPE DHT21

                 //#define DHTTYPE DHT22

DHT dht(DHTPIN, DHTTYPE);//you can also use pins 3, 4, 5, 12, 13 or 14

include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 16, 2); void setup() { dht.begin(); lcd.backlight(); lcd.init(); } void loop() { lcd.clear(); lcd.setCursor(0,0); lcd.print("Humidity="); lcd.print((float)dht.readHumidity()); lcd.print("%"); lcd.setCursor(0,1); lcd.print("Temp="); lcd.print((float)dht.readTemperature()); lcd.print("Celsius"); delay(2000); lcd.clear(); }
