With this plugin to Unity, you will be able to easily integrate and use all Android sensors, including those not supported by default in Unity. The tool set supports all standard Android API sensors as well as those provided by the hardware manufacturer of the device not defined by the Android API. The tool set also provides support for networking sensor values from an Android device to a build running in the Unity Editor, allowing the developer to quickly test and debug without having to constantly push new builds to a device.
This project is not currently released to the public. The project is a highly functional state, but needs more user testing, polishing and documentation before I would consider it ready for release.
