I was trying to display the readings of my dht11 sensor on the Blynk dashboard but I am struggling a lot. A little help would be really appreciated.
#define BLYNK_PRINT Serial
/* Fill in information from Blynk Device Info here */
#define BLYNK_TEMPLATE_ID "TMPL3cu_fjr1u"
#define BLYNK_TEMPLATE_NAME "DHT11 Example"
#define BLYNK_AUTH_TOKEN "bpPlBa8ehOqw0sJLKJeO1thMlulVXUCY"
#include <DHT.h>
#include <WiFi.h>
#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "***";
char pass[] = "***";
#define DHTPIN 2 // What digital pin we're connected to
// Uncomment whatever type you're using!
#define DHTTYPE DHT11 // DHT 11
DHT dht(DHTPIN, DHTTYPE);
BlynkTimer timer;
// This function sends Arduino's up time every second to Virtual Pin (5)
void sendSensor()
{
float h = dht.readHumidity();
float t = dht.readTemperature(); // or dht.readTemperature(true) for Fahrenheit
if (isnan(h) || isnan(t)) {
Serial.println("Failed to read from DHT sensor!");
return;
}
// You can send any value at any time.
// Please don't send more that 10 values per second.
Blynk.virtualWrite(V5, h);
Blynk.virtualWrite(V6, t);
}
void setup()
{
// Debug console
Serial.begin(9600);
dht.begin();
// Setup a function to be called every second
timer.setInterval(1000L, sendSensor);
}
void loop()
{
Blynk.run();
timer.run();
}
When I run this, it gets uploaded with no error, but Blynk shows that the device is offline and this is shown in the serial monitor of Arduino IDE:
