Arduino Temperature Sensor

Arduino weather station

Today, through this post, I will tell you how to build the Temperature Sensor Project or Weather Station with the help of Arduino.

DHT 11 Sensor -

DHT Module

First, collect these following Components 

• Arduino Uno                Buy on Amazon
• DHT 11 Sensor            Buy on Amazon
• 16X2 LCD Display        Buy on Amazon
• Jumper Wires
• Breadboard

So,

Follow this Steps

1) You create the circuit according to the circuit given in the picture given below.

2) Open Arduino ide Software and add Two library -

(Note: if you already installed this library so skip this step )

     DHT Sensor Master library {DHT.h} - Click here

LiquidCrystal.h - Click here

3) Restart Arduino ide Software.

4) Create a new file.

5) Copy the code given below and paste on Arduino ide Software.

Or

You can also download .ino File -

If you want to print the temperature in Celsius

#include<LiquidCrystal.h> #include<DHT.h> #define DHTpin 13 // DHT data pin #define DHTtype DHT11 // Type of DHT , DHT11 or DHT22 LiquidCrystal lcd(2,3,4,5,6,7,8); //Change the pin number of display DHT dht(DHTpin,DHTtype); /* Eccircuit * This code is for Temperature And Humidity Sensor * Made By Ankit jat * More Arduino Project Just click www.eccircuit.com * Join facebook page Eccircuit For More Projects */ void setup() { lcd.begin(16,2); Serial.begin(9600); dht.begin(); lcd.clear(); delay(1000); Serial.println("Weather Station"); lcd.print("Weather station"); delay(2000); } void loop() { float temp=dht.readTemperature(true); float humi=dht.readHumidity(); lcd.clear(); lcd.setCursor(0,0); lcd.print("Temp : "); lcd.print(temp); lcd.print(" F"); lcd.setCursor(0,1); lcd.print("Humi : "); lcd.print(humi); lcd.print(" %"); Serial.print("Temprature : "); Serial.print(temp); Serial.print(" *C"); Serial.print(" Humidity : "); Serial.print(humi); Serial.println(" %"); delay(2000); // change the value of refresh time } 6) You can also see the readings of temperature and humidity in the serial monitor.
Set the baud rate of 9600.

7) Compile And upload the code.
