Hi,
I've hooked an Arduino up wirelessly via Bluetooth, using a cheap
serial-to-Bluetooth adapter (TTL levels, cost ~$8). It'd be near-trivial
to hook sensors to the Arduino A/D inputs and send (plain text?) readings
over its serial port. On the "base station" all you'd need is a Bluetooth
adapter (often already built in, or a cheap USB dongle). Keeping it
on-topic, apparently there is a way to make two of the serial-to-Bluetooth
gizmos talk to each other forming a wireless serial bridge, so you could do
the monitoring on a piece of classic hardware with a RS232 input.

Cheers,
Joachim.

I'm wanting to add some wireless monitoring of
temperatures and power
on various devices throughout my brewery and I suspect someone on this
list is up to date on the technology which would work well and be a
good low cost starting point. I am mostly looking for guidance on the
best board to use for interconnect. I will take care of the programming
and any hardware modifications and/or additions. Is zigbee what I want?
I have fermenters, chillers, condensing units coolers, etc throughout
the building, so minimally one or so A/D inputs and possibly a couple
of digital inputs on the board should suit my needs. In the long run I
want to check on status from my smartphone as well as have the system
alert me if there is an alarm condition. If the "base station" is either
connected to our local network or plugs into a PC/mac, that should be
workable.
Thanks in advance...
