Wireless sensors without networking

I have tried to find a way to connect wirelessly about 20 simple sensors (on/off) to "Mini Maestro 24-Channel USB Servo Controller (Partial Kit) Pololu 1357".

I don't want to use complicated and expensive things like bluetooth or XBee etc.

I there any way to send some kind of pulse or something similar? Thanks

Using radio is just not that simple, hence why we have things like bluetooth. Just think it through, how will you know which sensor the signal came from?

if you have line-of-sight you could use infra-red or visible light but you will still need some encoding to know which sensor sent the signal.

I'm total newbie in these things.

Unfortunately there is not line-of-sight.

I'm pretty sure someone has developed this kind of comms circuit plan already.

What options i have? Using 20 bluetooth type of networking things like XBee is too expensive. Thanks
