Скачать или смотреть Arduino - Project 5 Humidity Sensor DHT11

Arduino is an open-source electronics platform that enables individuals, hobbyists, and professionals to create interactive projects and prototypes easily. Developed in Italy in 2005, Arduino has since gained immense popularity due to its simplicity, versatility, and accessibility.

At its core, Arduino consists of two main elements: hardware and software. The hardware comprises a microcontroller board equipped with input/output pins, which allow it to interact with various sensors, actuators, and other electronic components. The software, known as the Arduino Integrated Development Environment (IDE), provides a user-friendly interface for writing, compiling, and uploading code to the Arduino board.

#include DHT.h

#define DHTPIN 2 // Digital pin connected to the DHT sensor
#define DHTTYPE DHT11 // DHT 11

DHT dht(DHTPIN, DHTTYPE);

void setup() {

dht.begin();
}

void loop() {
delay(2000); // Wait for 2 seconds between measurements

float temperature = dht.readTemperature(); // Read temperature as Celsius
float humidity = dht.readHumidity(); // Read humidity

if (isnan(temperature) || isnan(humidity)) {
Serial.println("Failed to read from DHT sensor!");
return;
}

Serial.print("Temperature: ");
Serial.print(temperature);
Serial.print("°C\t");
Serial.print("Humidity: ");
Serial.print(humidity);
