- Forbo 8y agoHow battery intensive are accelerometers? The last fob I had required a battery change once every year or so already, increasing that frequency could be quite annoying. And I'd rather not have yet another device I need to regularly charge.
- taw123 8y agoAnecdotaly, I have a remote that lights up everytime it's moved (to assist finding it at night as it's a remote for a bed). I've had it for well over a year and haven't changed the batteries yet. Granted, it runs on three AAA batteries. Not entirely sure what tech it uses, but it's not necessarily a full blown accelerometer. Edit: some / all of the power drain would be offset because the RF transmitter would be off while the sensor is on.
- oh_sigh 8y agoNot bad at all, especially considering you would only need very coarse grained data, and not even that often. Years ago, McDonalds was handing out pedometers[1] which had a year+ battery life along with a display in a package smaller than most key fobs.
