About Accelerometer Test
Introduction
This page reads acceleration when the browser provides motion sensors. Desktops usually cannot. iPhone may ask for motion permission. Values are approximate and meant for a quick sensor check, not lab calibration.
What this tool does
It shows acceleration axes from device motion (or related sensor APIs) when available.
When to use it
Use it on a phone to confirm motion events arrive after permission.
How it works
Supported: many mobile Safari/Chrome builds. Unsupported: most desktops. Why: PCs lack these sensors for the web, and mobile OS gate access. Permissions: motion on iOS when prompted. Hardware: phone/tablet with an accelerometer. Expected: changing X/Y/Z while you move, or unsupported on desktop.
Step-by-step instructions
- Open the page on a phone.
- Allow motion access if asked.
- Move and tilt the device to see values update.
Common problems
Desktop unsupported is normal. Denied permission yields no readings until allowed in site settings.
Privacy explanation
Motion samples stay local. DeviceHub does not upload them.
