I try to show data temperature of DS18B20 on Blynk App, pls advise
*** Found point on graph is no data received , right
Code:
#define BLYNK_PRINT Serial // Comment this out to disable prints and save space
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <SimpleTimer.h>
#include <OneWire.h>
#include <DallasTemperature.h>
#include <stdlib_noniso.h>
#define ONE_WIRE_BUS 12 //go12 d6
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature DS18B20(&oneWire);
float oldTemp;
WidgetLED led1(16);
//WidgetLED led1(11)
//int relay =5;
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "4e983eff48c14a14b4efxxxxxx";
SimpleTimer timer;
void sendUptime()
{
delay(10000);
float temp;
DS18B20.requestTemperatures();
temp = DS18B20.getTempCByIndex(0);
Serial.print("Temperature: ");
Serial.println(temp);
while (Blynk.connect() == false) {
//digitalWrite(V3, LOW);
// Wait until connected
}
//digitalWrite(relay, HIGH); // relay on
// led1.off(); //led on
Blynk.virtualWrite(V2,temp);
Blynk.virtualWrite(V1,temp);
//led1.on();
}
void setup()
{
Serial.begin(9600);
//Blynk.begin(auth,"xxxx2015","xxx2015","192,168,0,35");
//Blynk.begin(auth, "wireless2012", "xxxx263A24451E100AE3AC");
Blynk.begin(auth, "xxxx2015", "xxx2015");
Blynk.config(192.168.4.1,80);
//Blynk.begin(auth, "xxxxx", "22222");
/**while (Blynk.connect() == false) {
// Wait until connected
}*/
// pinMode(relay, OUTPUT); //define to output
timer.setInterval(3000L, sendUptime); //1 sec
DS18B20.begin();
}
void loop()
{
Blynk.run();
timer.run();
}
