I am not very familiar with electronics and am wondering if someone can assist me or at least point me in the right direction. I am wondering if a micro computer chip, say smaller than a dime can easily be affixed to an object and transmit an alert (beeping noise) to a receiver or piezo sensor/speaker when the two are separated by say 10 feet? If this is possible the more smaller and compact the better. Thank you.

 

One post on the same topic is enough.

In future, try to make your title as descriptive as possible in few words.
