Also, it's all cabled together with inexpensive satin cable and RJ11 plugs, probably more reliable to use a powered hub though if you have more than a few sensors, but you can always try that later if you have problems. You do have to be careful which pin goes to ground or + it probably won't damage anything but the device will not be seen if you cross the wires. Cheap "biscuit" phone jack can be useful for testing and troubleshooting, that makes it easy to switch + and ground if you think that may be the problem. Finally, a use for all of that Mac PhoneNet / Gator / serial Terminal Server junk that you never quite got around to throw away, lol.
