(esp32+adxl325+sdcard)Storing sensor data in sd card(in txt file) and then sending it to cloud.

  2 3 0.0 C++

  This project shows how to use the ESP32 to interact with the MQTT protocol in the IoT environment. For more information, refer to the article https://bit.ly/3a3t7xq

I'd suggest sending data directly to AWS IoT Core (Free tier eligible) with the MQTT protocol. You can send data in JSON format. You could then use a serverless function to send that data to a DynamoDB (noSQL) database as the API is easy to use.

  ThingSpeak is an open source “Internet of Things” application and API to store and retrieve data from things using HTTP over the Internet or via a Local Area Network. With ThingSpeak, you can create sensor logging applications, location tracking applications, and a social network of things with status updates.

Thingsboard and thingspeak are some more user friendly alternatives that MIGHT help accomplish your goal, I've not used them before.
