Accelerometer Usage Suggestions

Commenters propose or debate using accelerometers, IMUs, and motion sensors as simple solutions for motion detection, interactions like secret knocks, or features in devices and apps, often questioning why more complex sensors are needed.

Can't they just use an accelerometer?

Seems like a good application for accelerometers as well.

This is fantastic technology. Is this based on accelerometer measurements?

Accelerometer and pressure readings could be useful.

How does it work? Some imu / accelerometer sensing?

khorwitz May 3, 2015 View on HN

This is beyond cool. Are there any known side-effects to the sensor?

raudette Apr 28, 2025 View on HN

Have you considered adding an IMU/motion sensor?

WiseWeasel Apr 2, 2014 View on HN

Maybe they want you to use the motion sensor for that.

Why not use accelerometer for that

godDLL Nov 22, 2021 View on HN

They have accelerometers, don't they? Can't it please be a SECRET KNOCK?
