ต่อ Soil Moisture หลายตัวอย่างไร อยากทราบวิธีต่อและโค้ดค่ะ esp8266

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

const int Relay = 5;
const int analogInPin = A0;

int sensorValue = 0;        // ตัวแปรค่า Analog
int outputValue = 0;        // ตัวแปรสำหรับ Map เพื่อคิด %





// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).

  // this method will be triggered every day
  // until you remove widget or stop project or
  // clean stop/start fields of widget
  Serial.print("Got a value: ");
  Serial.println(param.asInt());
  
  if(param.asInt() == 0)

  }

  {

  }
}


void setup()
{

  Serial.begin(9600);

  digitalWrite(Relay, LOW);
  Blynk.begin(auth, ssid, pass);
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 80);
  //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
}

void loop()
{
  sensorValue = analogRead(analogInPin);
  outputValue = map(sensorValue, 0, 1023, 100, 0);
Blynk.virtualWrite(V83, outputValue); 
  Serial.print("Soil Moisture = ");
  Serial.print(outputValue);
  Serial.println(" %");

}

Soil Moisture ใช้ตัวไหนต้องเอามาดูครับ
