Hiiiiiiii
I am doing a small project, for that I require a a small wireless communication kit which can communicate within the distance of one foot. my requirement is that transmitter and receiver should be placed one or atleast half a foot apart.

so if you know any such kit please let me know.
 

First could you let know what you exactly want to do? Control some thing sort of a remote controller or transfer a high speed data or some thing else? There are wireless options like TLP transmitters and receivers and too Xbee.
Cheers
 
Dear sir
The transmitter would be placed around one foot away from the receiver,
when an event is detected near the transmitter it should send message to receiver
and then receiver output will be given to take suitable action
 

Just have a look at the similar thread here

OR download HT12 based 4 channel TX and RX remote controller schematics here
 

Forget that cc2500 unit, you can get a TI ez430 (USB Interface) and use the free IAR software or a simple unit like: **broken link removed** (USB Interface) and use the digi XCTU software.
 

For such a short range, why not look at IR as an option? Would be much simpler/cheaper...

Problems with IR......lighting can cause false triggering...try a overhead flourescent light, you'll get data! needs optical filtering.
 

Not if you modulate the IR, and use a TSOP for stripping it away; ever seen household lighting get in the way of your TV remote? :)

Regards,

Anand
 

Never seen household lighting get in the way of a TV remote, because the reciever lens is optically filtered for 950nm.
