That's awesome!

I ordered a couple of them for myself. One to play with, the other I'm going to write some tests for after connecting it to my test platform.

After going through the code, your module uses WiringPi::API, but your cpanfile lists RPi::WiringPi. The latter requires the former, and since I don't see any usage of RPi::WiringPi anywhere in the code, might I recommend that you change your prereq to WiringPi::API instead? The installation of your distribution will go *much* faster if you do this.

RPi::WiringPi installs a whole slew of sensor, ICs and other peripheral distributions (Perl and XS) that takes quite some time. If you're not using any of the functionality of this encompassing distribution, it's best if you don't require it.
