Ultrasonic Sensor for Coding

#1

I want to use the ultrasonic sensor to prevent the drone from hitting the walls.

  1. Where is the ultrasonic sensor in the Main Block(top or bottom)？
  2. Which port(1-6) is it close to?
  3. It is used for measuring horizontal or vertical distance？
  4. What is the measurement(in cm or m)?

According to the specs (link) there is not one.
