Hi this is Graham from Jenham's Astro the chances are if you're interested in
astronomy you also have an interest in the weather so today we're going to have
a look at a weather station this particular model is the Bresser 5 in 1
weather center and we're going to open it up put it together and see
how it performs so inside the box you've got a set of instructions which are
pretty comprehensive and I'd say they're reasonably easy to follow you have a
unit that you place inside your house which gives you the readout of the data
from the weather station and we'll come back to that later and then you have the
main weather station itself which comes in one big lump so there isn't anything
to assemble it looks quite substantial but it actually only weighs just over
600 grams and the only other thing you've got to work out is how to to
mount this unit and you actually want to mount it vertically and you want to melt
it so that the wind direction is accurate and to do that a on top of the
unit there's an N basically telling you to mount this pointing it in a north
direction in order to mount it you've got a couple of options comes with a
bracket here which can clamp onto a post maybe you have and then the the foot on
the bottom of the weather station can either be orientated in this way to
mount on top of the post or it can be rotated in order to be clamped on the
other side of post with this being the the other part of the clamping device so
you've got a couple of options other than that you just got to put batteries
into the two units so we'll do that and we'll see how it performs
okay so what functions have we got so starting at the top we've got a display
at the current time and let's say it's got a radio connection to to pick that
up we've got the day and the date and an indication of the phase of the moon and
then in this area here we've got the indoor humidity and the outdoor humidity
coming in from the weather station this one against the indoor climate
humidity is little smiley face or sad face telling you if it's a comfortable
range or humidity or not over here we have the temperature both indoors where
this receiver unit is and outdoors where the weather station is and here we have a
symbol that tells you a prediction for the next twelve hours there's an
algorithm inside here which is predicting what the weather's going to
be like for the next 12 hours and then down here we've got an indication of the
barometric pressure and this is a history graph which is telling you the
trend of that barometric pressure we'll have another look at that in a moment
over here we have an indication for wind direction so this is coming in from the
weather station as the weather vane turns around in the wind and it's
telling you in this case that the wind is south-southwest then as a measurement
of the wind speed and an indication over that's light moderate strong etc and
then there's a Beaufort scale where that value is put against the Beaufort scale
so in this case it's very light winds one point eight miles per hour
and both the scale of one and then finally down in the corner there's an
indication of wind chill now down at the bottom of the panel you've got a series
of buttons and these show you some of the additional features of the weather
station so working from the left to the right there's a history button if you
press that it will tell you the values of the the data we've just looked at
every hour so you can step back and you look at the maximum minimum values
they were taken in there in that hour so it's quite a useful function and then if
you leave it it'll reset after a few seconds back to the current data you
also have a Max and min which is steps you through the parameters one by one
and shows you the maximum of middle values that it has stored since the unit
was last reset and you can see if you leave it running for quite a while you
get a good range of data for each of the parameters temperature humidity etc and
again if you leave the button unpressed it resets back to the current data over
here we've got four buttons that allow you to show more data for various
functions so the first one here is showing you about rainfall so if we
press that then this area is configured to tell you about rainfall and then it
can if you press it again you can see there's been 41.2 millimeters of
rain since I set the unit up and you can toggle through to see the rain in the
last hour day or week and last month so that's pretty clever
and you get a little graph of that data as well so you can see the trend the
next button tells you about the forecast weather and as you press that I toggles
through various displays of barometric pressure in different units and again as
a trend you can see if the pressure is rising or falling the next one is about
wind and it allows you to toggle between average wind speed and the strongest
gust that's been detected and then finally you can toggle this area down in
the bottom to show you either heat index
indoor dew point or the wind chill so the temperature outside taking into
account the value of the wind but because there's very little wind right
now it's the same value
okay so you might ask is the data accurate well I'm not able to check all
of the values but for a couple of them I can get an idea
so the indoor temperature that compares accurately to other thermometers have
got inside the house and for the barometric pressure again I've got a
barometer and the values are in good alignment you can set the unit up to
have a reference barometric pressure to allow for the altitude of where where
it's situated other than that the wind direction seems pretty accurate but I
say the wind speed probably you need to have quite an exposed spot for the wind
meter to work accurately I've got a small garden and probably the values
I've seen don't reflect the full strength of the wind because of the
effect of trees and fences and things like that so other than that I'd say
that all the data seems to have good correlation to the the weather forecast
you see all the news and data that you can you can compare sources
so final thoughts said it's a nicely thought out weather station quite easy
to use the instructions are clear although there's quite a lot of options
to set wind speed in miles per hour or in knots etc etc set your barometric
altitude so there's a little bit of configuring to do once you've got the
unit when you first get the unit set up but it's got a lot of capability it's
got some nice functions like it's got a backlight which comes on for a few
seconds you could also use the unit as an alarm clock if you wish and overall
I'd say it's easy to use gives you a lot of information and as far as I can judge
things like the history function and the weather forecast seems to correlate well
with the weather I can see out of the window so Bresser five-in-one
Weather Center seems to be a good good piece of kit ok thanks for watching
