Скачать или смотреть Temperature and Humidity using DHT11 3 pins ESP32 Tutorial

Sa video na ito tuturuan ko ko kayo pano paganahin, basahin ang values at i-connect sa ESP32 ang DHT11 humidity at temperature sensor.

Code:
#include "DHT.h"

#define DHTPIN 4 // GPIO 4 on ESP32
#define DHTTYPE DHT11 // DHT 11 sensor

DHT dht(DHTPIN, DHTTYPE);

void setup() {
Serial.begin(9600);
Serial.println("DHT11 Temperature & Humidity Sensor on ESP32");
dht.begin();
}

void loop() {
float humidity = dht.readHumidity();
float temperature = dht.readTemperature();

if (isnan(humidity) || isnan(temperature)) {
Serial.println("Failed to read from DHT11 sensor!");
return;
}

Serial.print("Humidity: ");
Serial.print(humidity);
Serial.print(" %\t");

Serial.print("Temperature: ");
Serial.print(temperature);
Serial.println(" °C");

delay(2000);
}
