I need the cheapest remote control (not IR) that counts with, only one button, about 100m span range, and being able to send an unique code different of another equal unit.
I need to have 300 of them working almost simultaneously.
And with a central unit connected to a PC (with a software made by me) reading all of them and identifying what units were button pressed.
Then, do you know some ready made product that meets the specs.
Or can you tell me what is the simplest design on what I can begin to work?
