I am looking for a short range wireless solution to transmit a single bit of data. I am working with a team of kids on a project and they want a remotely sensed event to be trasmitted no more than 10 feet. Optical system is not possible as line of sight is broken. What might be the simplest and cheapest solution? A micro on both ends of the link would be available.
My current solution is the pair:
https://www.sparkfun.com/products/10534
https://www.sparkfun.com/products/10532
But I would still need to transmit bytes and to prevent false alarms and an ID code. Bit too much for elementary and middle school kids.
Looking for something like a key fob door unlocker for just a few dollars. Any ideas?
