Hello everyone,
I am a college engineering student working on a circuits project, and I need some help. The project is to design a proximity device that sounds an alarm when a transmitter is out of range. The device includes a circuit with a transceiver that pairs with a small chip that includes a transmitter. The range of the device needs to be at least 20 feet (6 m). Preferably, the tranceiver circuit needs to include USB connectivity. Can any one point me in the right direction as to which products I need, and maybe how to approach this project? Thanks!
