Hi !
I’ve make teperature monitoring with 3 esp8266 and DHT11. All is working exept update. I need to up temerature for updating on blynk app.
I’m using local server on Pi 0.
- Pi 0 is not adapted for local server ?
- Time interval is to little ? ( 250 ms )
- Something else ?
My sketch :
#define BLYNK_PRINT Serial
#include <SimpleTimer.h>
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <DHT.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "xx";
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "wifi";
char pass[] = "xx";
#define DHTPIN 2 // What digital pin we're connected to
// Uncomment whatever type you're using!
#define DHTTYPE DHT11 // DHT 11
//#define DHTTYPE DHT22 // DHT 22, AM2302, AM2321
//#define DHTTYPE DHT21 // DHT 21, AM2301
DHT dht(DHTPIN, DHTTYPE);
BlynkTimer timer;
// This function sends Arduino's up time every second to Virtual Pin (5).
// In the app, Widget's reading frequency should be set to PUSH. This means
// that you define how often to send data to Blynk App.
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(V14, h);
Blynk.virtualWrite(V15, t);
}
void setup()
{
// Debug console
Serial.begin(9600);
Blynk.begin(auth, ssid, pass, IPAddress(xx), 8080);
dht.begin();
// Setup a function to be called every second
timer.setInterval(250L, sendSensor);
}
void loop()
{
Blynk.run();
timer.run();
}
