How to update the firebase using this library for esp8266

[desmonub]

Please help I'm trying to push data of three sensors to my real-time database using esp8266 and figure out the error's

CODE:

#include <Arduino.h>
#if defined(ESP32) || defined(ARDUINO_RASPBERRY_PI_PICO_W)
#include <WiFi.h>
#elif defined(ESP8266)
#include <ESP8266WiFi.h>
#endif

#include <Firebase_ESP_Client.h>
#include <DHT.h>

/* 1. Define the WiFi credentials */
#define WIFI_SSID "WIFI_AP"
#define WIFI_PASSWORD "WIFI_PASSWORD"

/* 2. If working with RTDB, define the RTDB URL and database secret */
#define FIREBASE_HOST "YOUR_FIREBASE_HOST" // e.g., yourproject.firebaseio.com
#define DATABASE_SECRET "YOUR_DATABASE_SECRET"

/* Define the Firebase Data object */
FirebaseData fbdo;

#define DHTPIN 2 // Digital pin connected to DHT11
#define DHTTYPE DHT11 // Initialize dht type as DHT 11
DHT dht(DHTPIN, DHTTYPE);

int Gas_analog = A0;

void setup()
{
pinMode(A0, INPUT);
Serial.begin(115200);
dht.begin();

WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
Serial.print("Connecting to Wi-Fi");
while (WiFi.status() != WL_CONNECTED)
{
Serial.print(".");
delay(500);
}
Serial.println();
Serial.print("Connected with IP: ");
Serial.println(WiFi.localIP());
Serial.println();

Serial.printf("Firebase Client v%s\n\n", FIREBASE_CLIENT_VERSION);

/* Initialize Firebase */
Firebase.begin(FIREBASE_HOST, DATABASE_SECRET);

/* Enable auto reconnect */
Firebase.reconnectWiFi(true);
}

void sendDataToFirebase(float temperature, int gasSensorAnalog, float humidity)
{
String fireTemperature = String(temperature) + "°C";
String fireHumidity = String(humidity) + "%";

FirebaseJson json;

// Set temperature, gas, and humidity values in Firebase JSON object
json.setFloat("number", temperature);
json.setInt("Gas", gasSensorAnalog);
json.setFloat("age", humidity);

// Convert JSON object to string
String jsonString;
json.toString(jsonString);

// Set the JSON string to Firebase
if (Firebase.setString(fbdo, "/players/John", jsonString))
{
Serial.println("Data sent to Firebase successfully.");
}
else
{
Serial.println("Failed to send data to Firebase.");
Serial.println(fbdo.errorReason());
}
}

void readFileFromFirebase()
{
if (Firebase.RTDB.getFile(&fbdo, mem_storage_type_flash, "/test/file_data", "/test.txt"))
{
// The file systems for flash and SD/SDMMC can be changed in FirebaseFS.h.
File file = DEFAULT_FLASH_FS.open("/test.txt", "r");

while (file.available())
{
  Serial.print(file.read(), HEX);
}
file.close();
Serial.println();

}
else
{
Serial.println(fbdo.fileTransferError());
}
}

void loop()
{
int gasSensorAnalog = analogRead(A0);
Serial.print("Gas Sensor: ");
Serial.println(gasSensorAnalog);

float humidity = dht.readHumidity();
float temperature = dht.readTemperature();

if (gasSensorAnalog > 300)
{
Serial.println("Gas");
}

Serial.print("Humidity: ");
Serial.print(humidity);
Serial.print("% Temperature: ");
Serial.print(temperature);
Serial.println("°C");

sendDataToFirebase(temperature, gasSensorAnalog, humidity);
readFileFromFirebase();

delay(1000);
}

Database secret is deprecated. Please follow these examples for how to authenticate and access the Firebase service as a user (client).

If you prefer to use database secret (legacy and insecure), please follow this example.
