Heading 1

Smart Umbrella is choose to improve existing umbrella. A humidity sensor senses, measures and regularly report the relative humidity in air it measures both humidity and air temperature as a percent in the ratio of actual humidity in the air to the highest amount of humidity air at that temperature can hold.

We can easily carry an umbrella with us so that we can see the temperature and humidity on it.

Components Required:

1. Arduino UNO

2. DHT11 sensor

3. LCD16*2 module

4. Breadboard

5. Potentiometer

6. Jumper wires

Programming Arduino For Smart Umbrella:

#include <LiquidCrystal.h>

#include <SimpleDHT.h>

//Declaring digital pin no 9 as the dht11 data pin

int pinDHT11 = 9;

SimpleDHT11 dht11;

//Declaring the lcd pins

const int a1 = 12, a2 = 11, a3 = 5, a4 = 4, a5 = 3, a6 = 2;

LiquidCrystal lcd(a1,a2,a3,a4,a5,a6);

void setup() {

//  serial monitor at 9600 

Serial.begin(9600);

//lcd to start

lcd.begin(16, 2);

}

void loop() {

//These serial codes are for getting readings on the serialmonitor as well as the LCD display, since they'll offer us a more detailed interface

Serial.println("=================================");

Serial.println("DHT11 readings...");

byte temperature = 0;

byte humidity = 0;

int err = SimpleDHTErrSuccess;

//This bit will tell our Arduino what to do if there is some sort of an error at getting readings from our sensor

if ((err = dht11.read(pinDHT11, &temperature, &humidity, NULL)) != SimpleDHTErrSuccess) {

Serial.print("No reading , err="); Serial.println(err);delay(1000);

return;

}

Serial.print("Readings: ");

Serial.print((int)temperature); Serial.print(" Celcius, ");

Serial.print((int)humidity); Serial.println(" humidity%");

//Telling our lcd to refresh itself every 0.75 seconds

lcd.clear();

//Choosing the first line and row

lcd.setCursor(0,0);

//Typing Temp: to the first line starting from the first row

lcd.print("Temp: ");

//Typing the temperature readings after "Temp: "

lcd.print((int)temperature);

//Choosing the second line and first row

lcd.setCursor(0,1);

//Typing Humidity(%): to the second line starting from the first row

lcd.print("Humidity(%): ");

//Typing the humidity readings after "Humidity(%): "

lcd.print((int)humidity);

delay(1000);

}

Application:

1. Automation leads to better monitoring of device.

2. Efficient and save time.

3. Save money.

4. Better quality of life.
