@TestDeveloper12345-7081 If your application has to react to events much quicker than this, consider using Blob Storage events . Blob Storage Events provides real-time one-time events which enable your Azure Functions or applications to quickly react to changes that occur to a blob.

You can rely on the Blob Storage events and read the sensor data using function app. More Info here: https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-trigger?tabs=in-process%2Cextensionv5&pivots=programming-language-csharp

If you wants to use the Logic App then they can leverage this: https://techcommunity.microsoft.com/t5/azure-paas-blog/add-file-watcher-on-containers-in-azure-storage-account-using/ba-p/1301993

Please let us know if you have any further queries. I’m happy to assist you further.

Hi @TestDeveloper12345-7081 ,
Here is a C# method to list all files in a blob container:

     public async Task ListAsync()
             {
                 // Get a connection string to our Azure Storage account.
                 string connectionString = ConnectionString;
        
                 // Get a reference to a container named "sample-container" and then create it
                 BlobContainerClient container = new BlobContainerClient(connectionString, Randomize("sample-container"));
                 await container.CreateAsync();
                 try
                 {   
                     // List all the blobs
                     List<string> names = new List<string>();
                     await foreach (BlobItem blob in container.GetBlobsAsync())
                     {
                         names.Add(blob.Name);
                     }
                 }
                 catch(Exception ex)
                 {
                     // Log the exception
                 }
             }

If you know the path of the file you want to download, then you can make use of the following method:

 public async Task DownloadImageAsync(string downloadPath)
         {
             // Download the public blob at https://aka.ms/bloburl
             await new BlobClient(new Uri("https://yourbloburl")).DownloadToAsync(downloadPath);
       
    
             byte[] fileBinary = File.ReadAllBytes(downloadPath)//you have the binary of the file so you can decide what to do with the file.
         }
