Sensor Can From simplehuman
Hands-free trash cans are great. What's not so great is if you have to do a wild hand-waving dance to get them to open or if, even worse, they slam shut while you are putting things in. Design-centered home goods brand simplehuman says that "innovation only makes sense if it's in sync with your needs" so they promise their sensor trash can won't unexpectedly open or close on you.
A little something called multi-sense technology keeps the can from having the drop on you. The trigger zone is a focused space directly above the lid which is precise enough to avoid false triggers. Once the lid is open, the bin enters task mode and the trigger zone extends to become more sensitive to activity, so the lid won't close before you're finished. After three seconds of continued activity, the lid automatically opens wider and switches to a 30-second stay-open mode. A natural charcoal filter is in the lid to help neutralize odors. The can will run up to 12 months with 6 high-quality alkaline C batteries, not included), or plug the can in with a power adapter which is sold separately. The 40L can is $225, the 48L recycler is $275 and the 55L is $275.
