Topic: how to implement an electronic tether (Read 137 times) previous topic - next topic


I am trying to create an "electronic" tether between a user and a moving device.  The concept I have is for the device to detect/measure the proximity of a particular individual who is 2 meters or closer.   I imagine it as some combination of a proximity sensor and and RFID sensor.  Has anyone successfully done something similar, or has anyone suggestions of how to approach such a challenge?  Thanks in advance for any input.


There are a plethora of Bluetooth devices available doing exactly this. Do you want to re-invent the wheel? Google for wireless keyfinder.


Thanks - I'll look.  I was clearly using the wrong search terms
