Simple Wireless Switch

Not open for further replies.


New Member

I would like to build a module that detects a number of separate wireless switches located across a room (maximum 16) either using RF, Bluetooth or some other transmission method that does not require a “point to point” view (ie Infrared) the maximum transmission distance is 30 ft.

The only Output I need from the transmitter is a simple on/off switch; with a corresponding LED to be lit on the Receiver unit i.e. transmitter switch 4 will light the LED 4 on the receiver...

Can anyone suggest the best way of approaching this??... is there a module or circuit out there that will allow me to do this??

Thanking you in advance for all of your help.
