An Effective, Economic, Aspirated Radiation Shield for Air TemperatureObservations and Its Spatial Gradients

College of Earth, Ocean, and Atmospheric Sciences, Oregon State University, Corvallis, Oregon

(Manuscript received 1 March 2012, in final form 24 October 2012

Construction requirements were to design a unit that uses inexpensive off-the-shelf components, to assembleeasily, to facilitate reconfiguration to accommodate various sensors, and to reduce power consumption with thegoal of reducing costs and enabling use in sensor networks in remote locations

I found this design rather interesting...  any thoughts??
Fits perfectly in the WeatherDuino DIY approach...

I think the double wall pipe has merit.

Well I decided to make my own version of the <Apogee Fan Assisted Radiation Shield>.
I'm lucky to have build a simple CNC machine so it was very straightforward to make but also without such a machine I think.

It's triple shielded and I need to paint it high gloss white OR use 'mirror adhesive foil'
Also It needs a large top cover plate.

The air is drawn from bottom to the top and by using smaller holes there is also airflow between the tubes to prevent heat building up.  If needed I can add some foam on the outside of the 50mm tube.

I think the design will work after studying the Apogee and R.M. Young FAR shields.

When finished and performing well, I will make it a project on <my Hackster page>

Nice job, it looks good.

Wow, looks great! Will look even better with some marine varnish on that ply.

Nice!

Hello,

Today I've received my new aspirated radiation shield - not DIY, but it made by professionals
from Hunan RIKA Electronic Technology:



I will change my old SHT21 sensor and my old DIY shield with this new one and SHT31
in the next weeks - I am already looking forward ...

I'd happily pay for a kit if you ever decided to make any available
