Understanding that range can be very dependant on environmental
conditions, does anyone know what the average expected range of the new
I.R. Buddy is?

Comments
I was just going to contact the list with information on the IR Buddy. We have
done several tests
to examine the range of the IR Buddy. It is truly dependent upon having line of
sight and little
infrared distraction. We have received a strong response from customers, so
perhaps list members
can email the list with their "range finding" research.
Here's the rest of the information-
++++++++++++
NEW! IR Buddy
#28016
$59 for a pair
++++++++++++
Parallax is excited to introduce the Infrared Buddy; a powerful accessory that
allows the BASIC
Stamp to transmit and receive infrared control codes, and communicate
(send/receive data packets)
with other BASIC Stamps. Amazingly enough, this is accomplished through a
single I/O pin and
without wires between devices.
HOW DOES IT WORK?
The IR Buddy has onboard IR transmit and receive hardware, as well as a
communications controller
that buffers incoming signals and manages data exchange with the BASIC Stamp.
APPLICATIONS
This device has tremendous potential for adding wireless capabilities to your
applications. Here's
a small list of ideas that can be realized with an IR Buddy pair, 2 BASIC
Stamps, and 2 carrier
boards:
1) Device controller using a standard television/VCR remote control
2) Fool-proof beam interrupt detection for alarm systems
3) Wireless data exchange between BASIC Stamps and IR master-slave control
KEY FEATURES
1) Simple, single-wire connection [noparse][[/noparse]bi-directional] with BASIC Stamp
2) 3-pin male header for connection to breadboards and standard 0.1" sockets
3) Auto-baud detection (2400, 4800, 9600) for Stamp-to-IR Buddy communications
4) Transmit RC-5 remote control codes; with programmable repeat and modulation
frequency
5) Receive RC-5 control codes; buffer up to four separate key press events
6) Send and receive buffered 8-byte data packets between BASIC Stamps through
wireless IR link
7) Loopback test checks Stamp-to-IR Buddy communications connection
8) Low current operation: 2 mA quiescent, 20 mA when transmitting
9) Sleep mode reduces current to 14 uA
RANGE
In absence of any infrared light (natural or "man-made"), the IR Buddy has a
range up to 100 feet.
Please note that the IR Buddy may have difficulties communicating in
environments with a significant
amount of infrared.
The use of the error accumulator allows the system to work in and be fine-tuned
for IR-noisy
environments. The implementation of random coded messages prevents defeat –
even from a duplicate
circuit because the extreme difficulty of synchronizing the counterfeit circuit
with transmitting to
the IR Buddy.

Thank you for the additional information. I understand the
limitations of I.R. communication, but I think we all needed to know some
basic or worst-case idea of what range to expect, in order to know weather
or not the I.R. Buddy could be a consideration for any given project or
idea. Thanks again for your help, the I.R. Buddy looks like another "did
your homework", well thought-out Parallax product. There are many of us
who really appreciate the Parallax "don't rush it to market" approach.

It is really difficult -- if not impossible -- to predict range under what
will always be variable conditions; there are just so many sources or IR that
can affect the receiver on the module. The IR Buddy is very robust though.
In the docs you'll find a Master-Slave example. I wrote those programs and
let them run in my office for several days, deliberately walking between the
devices [noparse][[/noparse]on my way to get coffee or a snack] and subjected both sides to
really heinous interference: like blasting them with a TV remote.
The pair did as I expected [noparse][[/noparse]designed], the devices would wait for the
interference to clear, then resynchronize and keep going. I would suggest
that the IR Buddy should be housed in the end of a cylinder to eliminate as
much interference as possible if you're going to be in a "noisy" environment.
This will narrow the field, of course, but that may also be desirable.

You're welcome. Hopefully Jon Williams' posting will suffice for now. Jon and
I will run some
tests with the IR Buddy set up when he's in our Rocklin office next week, then
we'll post our
results based on that sample.
Thanks for the kind remarks, we appreciate the feedback.

I would also be very interested in what could be considered the
reasonable effective range of an IR Gate with the IR Buddy -
especially under natural lighting as outside.
I'm looking to build a traffic logger and would be thrilled to
see 35' to 40' with such a setup.
I'll see if we can add this to the list of testing requests.
That's a great idea for an application.

application it would be best to shield the IR Buddy from interference. This
is easily accomplisehd by mounting it in the end of a cylinder. You could
use a piece of 2" PVC pipe and an end-cap to create an inexpensive enclosure.
