Hello guys, Welcome back to Artuino. As you have Seen I have started An Instructable
Today we are going to make a Temperature & Humidity meter with the DHT11 module. Let's get started
P.S. Consider Subscribing and liking the video
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Connection
Follow this Diagram
after connection, it will look like this
Step 2: Code
This is the code that I usd for my project
#include //include the lcd library
const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2; LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
#include "dht.h"// include the the dht sensor library
#define DHT_pin A0// give a name to the sensor pin and A0
dht DHT;//initialize the sensor
lcd.begin(16, 2);//initialize the senso
Serial.begin(9600);// start the Serial communication
delay(500);//Delay to let system boot
Serial.println("DHT11 Humidity & temperature Sensor\n\n");
delay(1000);//Wait before accessing Sensor
DHT.read11(DHT_pin);//Read the Sensor pin
Serial.print("humidity = ");//print the humidity in the Serial Monitor
Serial.print("temperature = ");
Serial.print(DHT.temperature); //to print temperature on the Serial monitor
lcd.print("humidity=");//to print humidity on the lcd
lcd.print("temp = ");//to print temperature on the lcd
delay(3000);//Wait 3 seconds before accessing sensor again.
Step 3: Output
I tried various things with it.
When I placed ice near it the temperature cooled down.
& and when a blew warm air into it, the temperature increased
