You should use Lambda with an S3 trigger to your bucket and edit the function code to check for the file type.

Eg. for Node JS use something like this:

  // Check that the file type is supported
  const fileType = typeMatch[1].toLowerCase();
  if (fileType != "txt" && fileType != "pdf") {
      console.log(`Unsupported file type: ${fileType}`);
      return;
  }

You can create an Event in the Amazon S3 console, which can then trigger a Lambda function or send a message via SNS or SQS.

This configuration accepts a prefix (effectively a directory) and a suffix (eg .jpg).

Simply open the bucket, go to the Properties tab and click Events (down the bottom).

See: Configuring Amazon S3 Event Notifications - Amazon Simple Storage Service

You can create multiple Events, each of which has a different suffix. But you can't create one Event with multiple suffixes. An alternative is to create an Event for any suffix (any file type), and have the Lambda function examine the filename and exit if it has an uninteresting suffix.
