II Quimestre 1ra Clase: Informática
MONITOREANDO VALORES
Clase del 11/09/2019
Aprendí la función del sensor de temperatura y humedad DHT11 y realizé la conexión del sensor con la placa de arduino. El sensor para que envíe la señal al motorreductor debe utilizar un componente por medio del cuál las ondas se intensificarán para que el funcionamiento del motor sea más eficiente.
Imagen de la práctica del sensor DHT11
La programación de arduino con respecto a la conexión es la siguiente:
#include "DHT.h"
// Uncomment whatever type you're using!
#define DHTTYPE DHT11 // DHT 11
//#define DHTTYPE DHT22 // DHT 22 (AM2302), AM2321
//#define DHTTYPE DHT21 // DHT 21 (AM2301)
// Connect pin 1 (on the left) of the sensor to +5V
// NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1
// to 3.3V instead of 5V!
// Connect pin 2 of the sensor to whatever your DHTPIN is
// Connect pin 4 (on the right) of the sensor to GROUND
// Connect a 10K resistor from pin 2 (data) to pin 1 (power) of the sensor
int DHTPin = 5; // what digital pin we're connected to
DHT dht(DHTPin, DHTTYPE);
void setup() {
Serial.begin(9600);
Serial.println("Moniteroando valores");
dht.begin();
}
void loop() {
// Wait a few seconds between measurements.
delay(2000);
// Reading temperature or humidity takes about 250 milliseconds!
float h = dht.readHumidity();
float t = dht.readTemperature();
if (isnan(h) || isnan(t)) {
Serial.println("Failed to read from DHT sensor!");
return;
}
Serial.print("Humidity: ");
Serial.print(h);
Serial.print(" %\t");
Serial.print("Temperature: ");
Serial.print(t);
Serial.print(" *C ");
if(t>26)
{
digitalWrite(9, HIGH);//encender motor
}
else
{
digitalWrite(9, LOW);//apagar motor
}
}
// Uncomment whatever type you're using!
