# Arduino-Serial-Data-Forwarder-to-ESP8266-IoT

Sending data from Arduino via serial communication to be forwarded by ESP IoT

ESP8266 has 1 Analog Input, so.. I forward Multiple sensor data from arduino (Ex. Arduino Uno) over serial communication to ESP8266 and push it to Firebase

Working library for this project:

1. Editor Arduino, `Version:2.3.2`

2. EESP8266 Board, `Version:3.1.2`

3. Firebase ESP8266 Client, `Version:3.2.2`

4. MQ7 Library (Optional) just for example.

   

Arduino Side :

1. Collect sensor data from analog port or other pin,

2. Print it using Serial using this format `data1,data2,data3,X`, data1 is sensor 1, data2 is sensor 2, data3 is sensor 3 then after comma separator print `"X"` then (enter) in arduino use `Serial.println("X");`.

3. example implementation bellow.

   ``` C

   Serial.print(data1);

   Serial.print(",");

   Serial.print(data2);

   Serial.print(",");

   Serial.print(data3);

   Serial.print(",");

   Serial.println("X");

   ```

4. Done.

Esp8266 Side :

1. Read incoming serial data from arduino. use array for data stream.

2. send it to Firebase

``` C

int data[3];

while (Serial.available()) {

    // get the new byte:

    char inChar = (char)Serial.read();

    if (inChar == ',') {

      data[urutan] = inputString.toFloat();

      inputString = "";

      urutan++;

      inChar = 0;

      goto jump;

    }

    // add it to the inputString:

    inputString += inChar;

jump:

    if (inChar == 'X') {

           for(int i=0;i<3;i++)

           {

             Serial.print(data[i]);

             Serial.print(",");

           }

      // clear the string:

      urutan = 0;

      inputString = "";

      // For running

      sensor1 = data[0];

      sensor2 = data[1];

      sensor3 = data[2];

      Firebase.setString(Data, "/yourFirebaseProjectBucket/yourFirebaseVariable1", (String)sensor1);

      Firebase.setString(Data, "/yourFirebaseProjectBucket/yourFirebaseVariable2", (String)sensor2);

      Firebase.setString(Data, "/yourFirebaseProjectBucket/yourFirebaseVariable3", (String)sensor3);

      delay(1000);

    }

  }

```

3. done

Enjoy All your arduino pin to IoT.
