ThingSpeak

where is the problem in this code, please help me..

esp 01 code-

#include "ThingSpeak.h" #include ESP8266WiFi.h

char ssid[] = "xxxxx"; // SSID here char pass[] = "xxxxxxx"; // Passowrd here

unsigned long Channel_ID = xxxxxxx; // Channel ID const char * myWriteAPIKey = "xxxxxx"; // Write API key

const int Field_Number_1 = 1; const int Field_Number_2 = 2; const int Field_Number_3 = 3; const int Field_Number_4 = 4; const int Field_Number_5 = 5; String value = ""; int value_1 = 0, value_2 = 0, value_3 = 0, value_4 = 0, value_5 = 0; WiFiClient client;

void setup() { Serial.begin(115200); WiFi.mode(WIFI_STA); ThingSpeak.begin(client); internet(); }

void loop() { internet(); if (Serial.available() > 0) { delay(100); while (Serial.available() > 0) { value = Serial.readString(); if (value[0] == '*') { if (value[11] == '#') { value_1 = ((value[1] - 0x30) * 10 + (value[2] - 0x30)); value_2 = ((value[3] - 0x30) * 10 + (value[4] - 0x30)); value_3 = ((value[5] - 0x30) * 10 + (value[6] - 0x30)); value_4 = ((value[7] - 0x30) * 10 + (value[8] - 0x30)); value_5 = ((value[9] - 0x30) * 10 + (value[10] - 0x30)); }

      }
    }
  }
  upload();
}

void internet() { if (WiFi.status() != WL_CONNECTED) { while (WiFi.status() != WL_CONNECTED) { WiFi.begin(ssid, pass); delay(5000); } } }

void upload() { ThingSpeak.writeField(Channel_ID, Field_Number_1, value_1, myWriteAPIKey); delay(15000); ThingSpeak.writeField(Channel_ID, Field_Number_2, value_2, myWriteAPIKey); delay(15000); ThingSpeak.writeField(Channel_ID, Field_Number_3, value_3, myWriteAPIKey); delay(15000); ThingSpeak.writeField(Channel_ID, Field_Number_4, value_4, myWriteAPIKey); delay(15000); ThingSpeak.writeField(Channel_ID, Field_Number_5, value_5, myWriteAPIKey); delay(15000); value = ""; }

if (moisture < 35) { digitalWrite(sensorPower, HIGH); // turn ON motor Serial.println("Motor is ON"); } if (moisture > 35 && moisture < 37) { digitalWrite(sensorPower, HIGH); //turn ON motor Serial.println("Motor is ON"); } if (moisture > 38) { digitalWrite(sensorPower, LOW); // turn OFF motor Serial.println("Motor is OFF"); }

 hasObstacle = digitalRead(obstaclePin); //Reads the output of the obstacle sensor from the 7th PIN of the Digital section of the arduino   
if (hasObstacle == LOW) //LOW means something is ahead
{
Serial.println("Something is ahead !!!");
}
else {
Serial.println("Path is clear");
}

Serial.println("--------------------------------------------------------------------------"); Serial.println("");

delay(3000); }

please help me to make this working for multiple sensors data.
