Electronic – arduino – Daisy chain (parallel) of IR sensors


I've got 5 little Sharp IR sensors I need to wire to an Arduino.

These are the sensors: https://www.sparkfun.com/products/242

Trouble is, I need to put the connections in a relatively small area.

Is there any reason I shouldn't "daisy chain" them together in parallel like this?

Each device has three terminals, not just the two that you show.

Yes, you can connect Vcc and Gnd in parallel to all of the sensors, but you'll need a separate Vo connection from each one to one of the analog input pins on your Arduino.
