Temperature Check using DHT11

Just  Arduino Things | TW TechieTube

Measure your room temperature and humidity easily.

Principle:

The electrical resistivity ratio between the electrodes where a substrate is placed in between them, It absorbs moisture from the atmosphere and the conductivity in it is represented as humidity and temperature

Components Required:-

• Arduino UNO                    (1)
• DHT 11 Temp. sensor        (1)
•  Breadboard                     (1)
• Jumper Cables                  (as per requirement)
• Arduino Bus Cable - ABC    (1)

Construction:-

A very simple project to check the atmospheric temperature using the DHT11 Sensor.

Now Connect the Sensor pins with the order given,

Vcc    - Arduino 5v/3.3v pin

Gnd   - Arduino Gnd Pin

DATA - Arduino Digital Pins  (We have given Digital output to print in               output)

As explained in the Video, the Code is written as follows,

Code:

#include <dht.h>

dht DHT;

#define DHT11_PIN 2

void setup()

{    Serial.begin(9600);

}

void loop()

{

int d = DHT.read11(DHT11_PIN);

Serial.print("Temperature = ");

Serial.println(DHT.temperature);

Serial.print("Humidity = ");

Serial.println(DHT.humidity);

delay(1000);

}
