Hello,
I have a problem regarding the blynk notification. I set up the notification on the blynk website on events but it doesn’t send the notification to my email. I’m not sure if the problem is regarding my code. The code I used is down below.
Here is the code:
#include <OneWire.h>
#include <SPI.h>
#include <BlynkSimpleEsp8266.h>
#include <DHT.h>
#include <DallasTemperature.h>
#define ONE_WIRE_BUS D2
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
char auth[] ="";
char ssid[] = "";
char pass[] = "";
int sensorValue = 2;
int sensorPin = 0;
#define DHTPIN 2
#define DHTTYPE DHT11
DHT dht(DHTPIN, DHTTYPE);
SimpleTimer timer;
void sendSensor()
{
float h = dht.readHumidity();
float t = dht.readTemperature();
if (isnan(h) || isnan(t)) {
Serial.println("Failed to read from DHT sensor!");
return;
}
if(t > 20){
Blynk.logEvent("temp_alert","Temp above 20 degree");
}
Blynk.virtualWrite(V5, h); //V5 is for Humidity
Blynk.virtualWrite(V6, t); //V6 is for Temperature
sensorValue = analogRead(sensorPin);
Blynk.virtualWrite(V2, sensorValue);
if (sensorValue > 50) {
Blynk.logEvent("I need water..");
}
}
void setup()
{
Serial.begin(9600);
dht.begin();
timer.setInterval(1000L, sendSensor);
Blynk.begin(auth, ssid, pass);
sensors.begin();
}
int sensor=0;
int output=0;
void sendTemps()
{
sensor=analogRead(A0);
output=(145-map(sensor,0,1023,0,100)); //in place 145 there is 100(it change with the change in sensor)
delay(1000);
sensors.requestTemperatures();
float temp = sensors.getTempCByIndex(0);
Serial.println(temp);
Serial.print("moisture = ");
Serial.print(output);
Serial.println("%");
Blynk.virtualWrite(V1, temp);
Blynk.virtualWrite(V2,output);
delay(1000);
}
void loop()
{
Blynk.run();
timer.run();
sendTemps();
}```
