Hi, I'm an expert Unity3D developer with extensive experience in AR and VR application for mobile, web and desktop platforms.
I worked before with gyroscope, accelerometer, microphone and other sensors.
Some SDKs for AR I've used are Vuforia, ARKit, ARCore, EasyAR, 8thWall, ARToolkit, OpenCV, and many other for VR and utilities tools.
Please write me and share more details about how you want to use accelerometer in your augmented content and thus be able to give you an excellent service.
