The goal is to get the sensor working. If you want to put that on a LCD display, that is the next step.
Your sensor is a type "AN":
Pin numbers:
pin 1 = the flat corner = GND
pin 2 = not connected
pin 3 = analog output to the Arduino board
pin 4 = not connected
pin 5 = not connected
pin 6 = 5V
That is not the same as you have.
