Change the description of the project on the project's site. It doesn't accurately represent the project's goals. it says

A JavaScript plugin that detects the client device's capabilities for support of several sensors like touch, motion and orientation sensors and also provides out of the box support for browser detection and OS/Platform detection.

But really the plugin checks for the support of JS sensor APIs. It doesn't check if the actual sensor is supported on the browser.
