title: Reading Analog Data from sensor connected to USB (Python)
body: <p><em>I may be confusing a few concepts here so any help is appreciated.</em></p>
  
  <p><strong>Q1</strong>: Is it possible to attach any sensor in the world to the USB on my computer as long as it gives me analog data, and read its output? (e.g. pH, temperature, oxygen sensor etc as long as it gives me analog data)</p>
  
  <p><strong>Q2</strong>: If so, then what is the simplest way in python for me read such data. </p>
  
  <p><strong>Comment</strong>: I am trying to bypass using PLC's, and trying to see if I can get the output from the sensor directly to the PC. (I do not have drivers for these sensors)</p>
  
  <p><strong>Actual Need</strong>: I have an oxygen sensor connected to my computer via a USB. The oxygen sensor is able to send out analog data. The obvious way is to go through a PLC. However, I would like a solution which by-passes PLC's so I can connect the sensor directly to my PC via USB.</p>
