is my station on a 20 foot wood post next to the barn. It has been up for a
year with zero maintenance.There is a second station about 25 feet up my 150
foot tower and it has constant maintenance. It also reads lower rainfall than
actual measured on other rain gauges. I think it needs a standoff to reduce
effects of tower.73 Keith NM5GSent via the Samsung Galaxy Note9, an AT&T 5G

Sensor Placement This made me wonder about sensor placement. I have had a
number of different wx stations and the instructions most provide for the
placement of the outdoor temperature sensor is to simply mount it on the north
side of the house just under the eaves. This kind of makes sense as it will be
away from direct sunlight but what about the heat from the house?How many do
this and does it work for you? Do your temperature readings match those or come
very close to an "official" local temp like at an airport.Has anyone else
noticed just how critical the placement of this sensor really is? I have 2-3
outside sensors in different locations and they all read differently, sometimes
as much as a 4F delta. I made sure they were all calibrated inside the house to
read the same then installed them outside. Once the sun goes down my readings
stabilize and my readings are within a degree of the "official" airport
temperatures. During the day, esp summer time the readings can be all over the
place.I know enough to keep them out of the sun, away from objects that can
absorb & retain heat, off the ground at least 10' or so, not above concrete,
etc......and yet I see big differences. So my question is where and how do
people mount their temperature sensors?Also does anyone know where and how the
"official" temperature sensors used by the NWS are mounted in places like
airports?Gedas, W8BYAGallery at http://w8bya.comLight travels faster than

my wife, who is a Weatherbird, seven years ago. As I recall, it was a six

performed on it is remove a seed (from my neighbor’s tree) that blocks the flow
of moisture through its self-emptying range gauge. It has a solar panel that
recharges the unit’s rechargeable batteries. I have yet to change them.>> The

this package. Not a cheap station, but one my wife has been happy with, as the
base unit sits on a end table by her chair in our living room. She checks the
base station five or six times a day when she’s not monitoring the Weather
Channel or the ND DOT online.>> 73,> Mike>
