Hello Everyone,
Im currently working on a project and need some help starting up. I want to design an anti-lost alarm/pager circuit composed of a transmitter and receiver. When the receiver is seperated from the transmitter at 7 feet it should sound off an alarm. It needs to use RF and needs to be small as possible. I want the transmitter to run off 5v supply and the receiver can run off any voltage.
I dont know where to begin. What type of transmitter should I use? What type of parts will I need to accomplish this?
