Wireless RF Switches

Hi,

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.

Regards

Re: Wireless RF Switches

This is exactly the type of application ZigBee was developed for. Microchip has a nice product offering including hardware, a Free Zigbee stack and several demo/development boards. You should check out their "Zigbee Design Center" at: **broken link removed**

Hi GSM Man,

Thank you for your post... I was not aware of Zigbee before this and this is definitely something I will investigate further...

My only major concern right now is the cost of the individual components, is there a cheaper alternative?

My plan was to link the Receiving unit to Arduino, so that when a switch is triggered a suitable "program/subroutine" is run, i noticed that the Zigbee stack has it's own PIC components.... can you just purchase the transmit/receive modules and link them to Arduinio?? or something similar??

Thanks again for your help, it is most appreciated.

Regards

Ajay
