Alright, that may be the wrong name for it but I am needing some type of circuit to detect when another sensor is near it... Like, when sensorA is within 5 feet of sensorB to activate a circuit on sensorA side...
Sorry if that sounds confusing... I need this for 2 different projects really. Would this fall under Radio Control or something else? Also, I need it so the sensors can't easily be activated. I want only sensorB to activate sensorA and nothing else can trigger it. Hope that makes sense... but to give you a better idea, one will be a vibrating collar for my wife's dog when it gets near my cat (stupid dog has killed her entire litter and is working on trying to get her now)
The other project is going to be a sensor on a keychain so my truck will know when I get close to it... within a few feet or something. I'll have several functions running off of it. I really will have it set so I can use the truck without the key.
