Wireless "wire"
Wireless "wire"
(OP)
Hi, I was wondering if anyone had a "low cost" solution in creating a system to read a 0-5V AC signal and wirelessly transmit then "reproduce" the signal. I need "high" accuracy, say +- 0.5%

RE: Wireless "wire"
Semiconductor level?
Module level?
Boxed Solution level?
Define "low cost"
There are solutions for all, but your question begs for clarification.

There are basically two types of Bluetooth (BT) modules:
HCI or "host controller interface". This is a very basic and cheap module that requires that you put most of the BT protocol stack firm/software) in your host controller. Only viable if you are planning to produce 50k+ units due to excessive cost of test equipment and certification (FCC, R&TTE etc.).
Port Replacement Module. This additionally features an onboard controller containing the full BT stack. You interface to the module via a CMOS UART using AT-commands (Hayes), just like a modem. No certification issues, these modules can be used out of the box as they are already certified. I would go this way in your place.

I would be interested in this too, but I am after a 4-20ma bluetooth system. Basicly I need to get a current loop signal 30m (100ft) to a small LCD display box. Do you think you could kill two birds with one stone and help us both out?
Thanks in advance.
