Hi,
That's great knowledge shared by you about the dht 11 it's two side work as a humidity and temperature also ..
Thanks for this tutorial

dht11 sensor code with arduino
/*
#include <Wire.h>
#include <LiquidCrystal_I2C.h>

LiquidCrystal_I2C lcd(0x27, 16, 2);


#include <DHT.h>
#define DHTPIN 3
#define DHTTYPE DHT11

DHT dht(DHTPIN, DHTTYPE);

void setup() {
lcd.init();
lcd.backlight();
Serial.begin(9600);
dht.begin(); // initialize the sensor
}

void loop() {
// wait a few seconds for start a measurement
delay(2000);

// read humidity data
float humidi = dht.readHumidity();
// read temperature data as Celsius
float tempC = dht.readTemperature();
// read temperature data as Fahrenheit
float tempF = dht.readTemperature(true);
// check if any reads data failed
if (isnan(humidi) || isnan(tempC) || isnan(tempF)) {
Serial.println("Failed to read from DHT sensor data!");
} else {
Serial.print("Humidity: ");
Serial.print(humidi);
Serial.print("%");

Serial.print(" | ");

Serial.print("Temperature: ");
Serial.print(tempC);
Serial.print("°C ~ ");
Serial.print(tempF);
Serial.println("°F");
lcd.setCursor(0, 0);
lcd.print("Humidity: ");
lcd.print(humidi);
lcd.print("%");
lcd.setCursor(0, 1);
lcd.print("Temp: ");
lcd.print(tempC);
lcd.print(" °C ~ ");
}
}
