Each sensor output will connect directly to an Arduino pin. It will also need feeding with +5V and wire up a common ground.

However, there is nothing on the page to tell you what pins are what but you should be able to tell easily from looking at the board.

EDIT - A closer look at the picture shows two pins marked Vcc and GND, along with a regulator. Therefore to power this you don't need 5V but any voltage from 6.5 to 15. I notice there is no capacitor on the input, this is a bit penny pinching and I would fit one on both input and output of the regulator.

do i need analog or digital input?

If it's TTL, then digital.
