Assuming Z axis is "up", you'll need one of these for the X and the Y axis to catch all relevant tilts. It's probably not cost effective or practical to make a 2-dimensional detector, but I imagine you could.
- mike_d 7y agoI used these when we would ship servers off to edge sites. You end up putting 5 or 6 of them on the box... tilt sensors on two sides, impact sensors, and temperature/moisture to make sure they haven't been left out on tarmac/loading docks. $100 in stickers on a $xx,xxx shipment is an easy justification. In practice they aren't hard for a motivated person to reset, but they do result in handlers along the way being a bit more careful with your stuff.
- nneonneo 7y agoIt’s all about raising the bar for mishandling. Sure, if an unethical handling company messes up your shipment they could go at it and try and reset the indicator(s), but they could also just get the job done right and not risk getting sued if the client does detect the tampering. On the other hand, without indicators there’s nothing stopping them from pretending they didn’t just throw your box around...

- SAI_Peregrinus 7y agoEspecially since these stickers (and those like them) have serial numbers, and the sender typically notes the serial numbers in an email or similar when the item is shipped. The effort required to reset one without it being noticed is pretty high.
- WorldPeas 7y ago>In practice they aren't hard for a motivated person to reset but a person who mishandles boxes wouldn't seem to fit that description. Foolproof.
- dfox 7y agoThere are two reasons why you would ever want to use something more complex: determining when the triggering happened (ie. who to blame) and ascertaining after the fact whether the trigger event was really meaningful for the package contents. You can build such an electronic sensor and it even can be cheap if reusable, but it mostly is not cost-effective. On the other hand trying to build such an thing is good source of interesting stories, like sales reps of three different semiconductor manufacturers calling you at 4AM and wanting to know what the hell you are designing and whether it in fact is not missile guidance system or some other ITAR covered thing...
