Outdoor Weather Satellite
The outdoor weather satellite
collects all of the data from the instruments on our weather pole and transmits the data to our mesh network. All
the components that make up this
satellite must fit in a weather-tight box
like the one shown in Figure 12. If you
followed along with this series, you
saw how I built a weather station
using various 1-Wire components. We
will utilize this interface as well with
our outdoor weather satellite. The
main advantage that we gain is that
once the DiosPro is programmed, you
need only supply 7-12V to the pole
and the rest is done for you. You may
also use a battery and a solar cell to
remove even these requirements.
You will need the following
components for the outdoor weather
■ FIGURE 13
DiosPro to create some
sort of moisture meter.
In Part 3, I will
take you step-by-step in
building this satellite.
• DiosPro 28 chip
• Dios Carrier 1 kit (Note: This is built
with the headers facing up.)
• Xbee module
• XBee interface board
• SchmartBoard jumpers
One of the advantages of building a
wireless weather station is
that you can tap into any of the data
being transmitted. I have created a very
simple protocol and various DiosPro
and PC routines to parse the network
data for just about any display system
you might want to include.
• SchmartBoard .1” prototype board
• 5V regulator chip
• Two 100 µF capacitors
• .1 µF capacitor
• 1K resistor
Since space is at a premium with
the outdoor satellite, you need to
build the Type 4 XBee interface board.
You can find a complete application
note explaining the process at www.
The LED display shown in Figures
13 and 14 is a Dios LCD board with
a XBee module mounted on the
bottom, using one of the various
interfaces. This particular display uses
a single button to toggle through the
many different display items. It even
counts lightning strikes collected by
the outdoor satellite and keeps track
of rain fall totals.
I also used a SmartBoard prototype board to build a one amp regulator, as well as the 1-Wire bus interface.
There is plenty of room on this board
for any other circuitry you might want
to add to this satellite. For instance,
you may want to use the built-in 10-bit
A-to-D (analog-to-digital) ports on the
The display in Figure 15 is the
same LCD carrier board, but it has
a graphic LCD attached. In this
particular display, I collect the data
given by the indoor satellite and
display a 12 hour forecast.
Figure 16 shows a BetaBrite LED
sign connected to a Dios Carrier
board that scrolls real-time weather
data across the screen.
The beauty of these displays is
