How to make a proximity sensor to sound an alarm when another sensor is with in 5 to 10 ft Answered

I am needing this to keep two people apart....It would basically be the opposite of a child proximity alarm, instead of sounding an alarm when the child is too far away, it would sound when it is too close .....Thanks for your help


Sounds like they might be self alarmed and you can maybe tell when they are too close by the yelling?

usually by the time they are yelling it is too late...this is a home where people w/ disabilies lives and we need this to alert the people that help them that they are too close

Have you considered a restraining order?
