No shown sensor value on my blynk app

Need Help With My Project
1

the sensor values don’t appear on my blynk app (on the gauge) i can’t find any solution please help

#define BLYNK_PRINT Serial

#include <WiFi.h>

#include <WiFiClient.h>

#include <BlynkSimpleEsp32.h>

#define BLYNK_TEMPLATE_ID "TMPL2PLZZiL_b"

#define BLYNK_TEMPLATE_NAME "smart irrigation"

#define BLYNK_AUTH_TOKEN "3C6zm-5qzPxEDoAtD5Y7djowVP8MkGEN"

char auth[] = "3C6zm-5qzPxEDoAtD5Y7djowVP8MkGEN";

char ssid[] = "";

char pass[] = "";

// Pin assignments

const int rainPin = 32;        // rain sensor pin

const int soilMoistPin = 26;   // soil moisture sensor pin

const int pumpPin = 13;         // pump control pin

// Thresholds

const int soilMoistThreshold = 100;  // soil moisture threshold

const int rainThreshold = 100;       // rain sensor threshold

// Blynk virtual pins

const int soilMoistVpin = 1;

const int rainVpin = 2;

const int pumpVpin = 3;

// Pump state

bool pumpState = false;

BlynkTimer timer;

void setup() {

  Serial.begin(9600);

  pinMode(rainPin, INPUT);

  pinMode(soilMoistPin, INPUT);

  pinMode(pumpPin, OUTPUT);

  Blynk.begin(auth, ssid, pass);

  // Set up timer to run every 5 seconds

  timer.setInterval(5000L, sendData);

}

void loop() {

  Blynk.run();

  timer.run();

}

// Function to read the sensors and send data to Blynk

void sendData() {

  int soilMoistValue = analogRead(soilMoistPin);

  int rainValue = analogRead(rainPin);

  bool isRaining = (rainValue < rainThreshold);

  bool isDry = (soilMoistValue > soilMoistThreshold);

  // Update Blynk app with sensor readings

  Blynk.virtualWrite(soilMoistVpin, soilMoistValue);

  Blynk.virtualWrite(rainVpin, isRaining ? 1 : 0);

  Blynk.virtualWrite(pumpVpin, pumpState ? 1 : 0);

  // Turn on/off the pump based on sensor readings

  if (!isRaining && isDry && !pumpState) {

    digitalWrite(pumpPin, HIGH);

    pumpState = true;

   

  } else if ((isRaining || !isDry) && pumpState) {

    digitalWrite(pumpPin, LOW);

    pumpState = false;

   

  }

}

i can’t solve this problem

@MIMOU Please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:
```

Copy and paste these if you can’t find the correct symbol on your keyboard.

Pin 26 is connected to ADC2, which cannot be used at the same time was WiFi.
Read this for more info…

As far as your other issues are concerned, I would suggest that you add some serial print statements to show you the values that you are getting from the sensors.
You should also share info about the virtual datastreams that you’ve created, especially the minimum and maximum values.
