Premise : Due to family reasons, we need Cisco (the family dog) to stay downstairs and not climb the stairs to the second floor. Cisco is a good dog and normally does not do this - but occasionally he will sneak up to the second floor and then hide somewhere.
I would like to put a RF or Magneto Acoustic tag like this, which is commonly put on store items, on his collar and install an alarm on the stairs which goes off when Cisco climbs the stairs.
I am fairly well at soldering circuit boards and have done small “projects” like this before. My first preference will be to buy a ready made solution, if it exists, the second option will be to mod an used system bought on ebay and the third option will be solder something from scratch like Aarduino.
All help on making this alarm appreciated.
Please do not post other methods of restraining Cisco downstairs in this thread - please start a new thread if you would like to do so. Please keep this thread dedicated to designing or hacking a system that does the same job as a supermarket store EAS system
