Is there a way to access WiFi-1010 sensor data direct to the Arduino cloud?

[zjones24]

I have what is a weather station on a Wifi-1010; temperature, humidity, and a switch state. I view this data remotely on my smartphone using the LightBlue app. I want to post this data to the Arduino Cloud without adding more hardware. Is there a way to do this? It appears the LightBlue app can post the data to AWS or Azure, but I don' really want to use those services.

It looks like the hardware you have is compatible with the Arduino cloud, so it should be able to send data there. What code do you have running to provide weather station functionality?

Here is the code. It controls a SHT-22 temperature/humidity sensor, monitors the state of a hall effect sensor, and the battery voltage.

/*
Smart Shield (Temperature (Centigrade), Humidity (%), tamper detection (1=container is open), and battery monitor (%)) with BLE connectivity
*/

#include <ArduinoBLE.h>
#include <Wire.h>
#include "SHTSensor.h"

SHTSensor sht;

const int buttonPin = 2; // set buttonPin to digital pin
const float REFERENCE_VOLTS = 3.3f; // +3.3V regulated supply voltage
const float R1 = 330000.0f; // Resistor values of voltage divider
const float R2 = 1200000.0f;
const float RESISTOR_FACTOR = 4095.0f * (R2 / (R1 + R2)); // Using 12-bit resolution: multiply by 4095

// create service:
BLEService SHT4XService("0x44");

// create characteristics and allow remote device to read and get notifications:
BLEIntCharacteristic Temperature("0x44", BLERead | BLENotify);
BLEIntCharacteristic Humidity("0x44", BLERead | BLENotify);
// create button characteristic and allow remote device to get notifications
BLEByteCharacteristic buttonCharacteristic("19B10012-E8F2-537E-4F6C-D104768A1214", BLERead | BLENotify);
BLEUnsignedCharCharacteristic batteryLevelChar("2A19", // standard 16-bit characteristic UUID
BLERead | BLENotify); // remote clients will be able to get notifications if this characteristic changes

}

}

// set the local name that the peripheral advertises:

}

  Serial.print(F("Battery Level: "));                    // Display the results
  Serial.print(volts);
  Serial.println(F("V"));
} else {
  Serial.print("Error in readSample()\n");

}
delay(1000);
BLEDevice central = BLE.central();

// if a central is connected to the peripheral:

// print the central's BT address:
Serial.print("Connected to central: ");
Serial.println(central.address());
// turn on LED to indicate connection:

// while the central remains connected:

   buttonCharacteristic.writeValue(buttonValue);
  }
     
  int batteryLevel = analogRead(ADC_BATTERY);               // Read the battery level from the ADC
  batteryLevelChar.writeValue(batteryLevel);  // and update the battery level characteristic

// turn off the LED

    }
