Oregon Scientific BAA968HG - Sensor positions
 

Ok, so I've just bought one today and have an issue with where to put the
sensors. They are bright white with a digital display on them. The problem
with this is that they appear very pinchable and I guess I'll have to buy
some sought of a screen to put it into.

I wondered if anyone has come up with an ingenious idea to disguise them.

Currently it's sitting on my garden seat reading a temperature of -2.9C
which I doubt is correct.

Now that's one problem I didn't think of! Plant a bush in front of it (but only
one that's exactly 2m above ground level ;) ).

My experience is that these sensors are a bit temperamental anyway - one of the
three in my kit is entirely useless, while one won't transmit to the base unit.
The final one sits in my garden in the best possible position I could find, and
thankfully seems to work!

I suppose you could get some khaki(sp) paint???

More lazy than ingenious - but it works for me. Take a plant pot (about 4 or 5"
size), paint it white to encourage reflection of any direct sunshine. The holes
in the bottom of it provide a degree of ventilation. Wedge the sensor inside,
with pot on side (keeps rain out). You now need an evergreen but well
ventilated hedge - that might be the tricky bit! - it is important to keep
sunshine at bay and to keep it (pot) away from any surfaces that may absorb
heat in the daytime and release it at night. Insert pot on its side into
aforementioned hedge / evergreen tree.

A better alternative, advocated by others on this NG, is to buy a set of round
drip trays that you normally but flower pots in. Assemble into a vertical stack
(with rods), allowing a gap between each one, cut out middle of all but the top
and bottom ones - to make a shaded but ventilated cavity - paint white and you
have a homemade screen that should be food enough to sit in the sun and not
'overheat'.. Apols for having forgotten who came up with this idea - I remember
a link to a webpage. Hopefully he/she will respond later. That was a bit
advanced for me!

The important thing is to get a sense of how your temps should compare with
nearby sites. If you reveal your location, I am sure NG members will help to
comment on any temperatures you record and to discuss how your site might be
expected to compare with local official sites. .

Thanks!!! Actually mine IS 1.5m, but more by accident of geaography than
anything.

If temps are measured at 1.5m, then why do GFS etc quote 'T2m'?

I have a similar unit.
Sensor one, is cable tied to our imitation
water pump windmill (like the wind pumps in america
but only 6 foot tall).
Just underneath the top platform so it never gets heated by direct sunlight.
Sensor two, is on a small bracket arrangement, just touching
the grass.....this unit has so far lasted 14 months on its batterys
although it sees the greatest amount of cold/damp/slugs/earwigs).
Sensor three is stuck to the inside of the windscreen of my car ... gives
me an early ice warning ... so i have time to scrape down before work!!

Because temperatures at 1.5 m vary much more from place to place than
temperatures at 2 m over the ground.

More or less what I did. The "bush" is growing in front of a NW facing
fence, and the plant pot is screwed to a fence post. A second plant pot,
smaller than the first is wedged inside the main one to make a rainproof
ventilated enclosure.

It is located about 10 feet from the NE wall of the house, which means that
it is in shade most of the time. This is the shadiest corner I could find
within range of the base unit in the house.

The only problem is early mornings in the summer, when the sun can shine on
the other side of the fence. This can cause the sensor to overread by
several degrees (compared to my other sensors and thermometers) despite the
air gap between the fence and the sensor. I have even seen summer days where
this sensor recorded its maximum at around 8am!

Apart from that, this is ny most reliable sensor position (compared to
readings from local weather stations).

I have one of their mini-screens - minima readings seem OK, and maxima
in winter, but read several degrees too high in summer.
