Circuit for 4 x Sharp IR GP2D120 Distance Sensor

Hi there,

For my current project I need to set up four Sharp IR GP2D120 Distance Sensors with my Arduin Eleven (essentially Arduino Uno). I have read that to reduce noise you can add capacitors to the circuit, so I am currently following the design from: http://letsmakerobots.com/node/22781?page=1

It seems fairly simple and I just want to double check that my circuit diagram is correct (its attached below).

Also, I read on another post (GP2Y0A2YK0F Sharp Distance Sensor) to use a capacitor and a resistor. I know that that was a different sensor to mine but I found a lot of sites referencing this post and saying it was the best way to do it. So what do you guys think?

Thanks in advance!
