Ok, advanced project. Detecting the presence/absence of my trash can. "We" have a problem remembering to bring down the trash can (and on alternate weeks, the trash and recycling can) The can is parked on the side of the house, generally in the same spot in the grass. The Trash can has a larg…

Could you mount a contact sensor on the side of your house and a magnetic strip on the bins? Then as long as the bins are pushed up against the house it would register that they are there.

The bigger question is why the blue lid is on the green can and the green lid is on the blue can... :smiley:

[image] neonturbo: why the blue lid is on the green can and the green lid is on the blue can... :exploding_head: I really like the magnetic strip or magnet attached to the trash can and contact sensor on the house. Simple and highly reliable, as long as the person(s) returning the trash can …

[image] danabw: as long as the person(s) returning the trash can know where to put it. And if not a simple reminder from HE if the trash can has been absent for X hours should help.

This problem is solved! Next! :grinning::+1:

I made an ultrasonic parking assist/stop light with an Arduino for my wife's car in the garage. The ultrasonic sensor would have no problems detecting the hard plastic can within a certain range. Perfect placement wouldn't be necessary.

Curious why the lids are reversed. A simple thought (or two): Ultra sonic sensor. I have one (I made) in the garage to sense if my vehicle is in the garage. When I come home at night, open the garage door a tilt sensor sets off an ultrasonic measurement to turn all the outside and some inside…

Cool, but ours would never make it back on the pallets. Our garbage is picked up by trucks with mechanical "arms". When putting the cans back down they are always offset from the original location.

[image] JohnRob: offset That's a gentle way of referring to it...we're lucky if our trash/recycle/greens cans are within four feet of their original location! :slight_smile:
