Dear Forum members,
I am looking for a RF circuit which is similar to a device used in the movie Wedlock (released in 1991).This is a circuit in which there are 2 circuits (electronic neck collars) connected by RF.As soon as these 2 get separated from each other by a specific Radius of Distance...they sound Alarm.I would like to make such a project for security and safety of children who play outside homes.The base circuit can be kept at home in front of a parent and the other with a child.As soon as the child goes away outside the Specified distance,the alarm sounds at the other device which is kept with the Parent at home.
Can someone please suggest me a circuit idea for the above device which can operate in the Radius of minimum 500 meters...
Thanks
