Temperature and Humidity

Temperature and Humidity

Components:

1- Arduino

 

2- Humidity and Temperature sensor module

 

3- 1k resistor

 

4-Wires

Connections:

Data pin : pin 3

Gnd : 1K Resistor :Gnd

Vcc : 5v

Code:

#include <dht.h>

// Define the DHT11 sensor pin
#define DHTPIN 2

// Create a DHT11 object
dht DHT;

void setup() {
  // Start the serial communication
  Serial.begin(9600);
}

void loop() {
  // Read the temperature and humidity from the DHT11 sensor
  int chk = DHT.read11(DHTPIN);

  // Check if the reading was successful
  if (chk == DHTLIB_OK) {
    // Print the temperature and humidity to the serial monitor
    Serial.print(“Temperature: “);
    Serial.print(DHT.temperature);
    Serial.print(” °C, Humidity: “);
    Serial.print(DHT.humidity);
    Serial.println(“%”);
  } else {
    // Print an error message if the reading failed
    Serial.println(“Error reading DHT11 sensor”);
  }

  // Wait for a short period of time before taking another reading
  delay(2000);
}
