Is pinsensor equal to zero?

The screenshot of your MIT-App seems to have more things above and below that can not be seen in the screenshot.

The part that of the MIT-App-code that is readable is not about processing this part of your arduino-code

        client.println("HTTP/1.1 200 OK");
        client.println("Content-Type: text/html");
        client.println("<!DOCTYPE HTML>");
        client.println("<html>");
        client.print("\n");
        client.println(counter);

How should anybody help if you give only partial information?

No, it should indicate above the number 0

5

Your observations indicate it is ZERO. Find why it is zero.
