Introduction: DS18B20 Radiation Shield
This is a mini tutorial. This radiation shield will be used in my instructable "Arduino Weathercloud Weather Station". Solar radiation shield is very common thing used in meteorologic stations to block direct solar radiation and therefore reduce errors in the measured temperature. It also acts as a holder for the temperature sensor. Radiation shields are very useful but are ussualy made from stell and they are expensive so I decided to build a shield of my own.
Step 1: Parts
Step 2: Usefull Tools
3mm and 6mm drill bits
Step 3: Drill Holes Into Plates
At first we need to drill holes into the plates. We have three rods, so it will be a equilateral triangle. Sketch the triangle to plates with marker. Then drill 6mm hole in every corner of triangle. Also drill 3mm holes in center of two bottom plates and 6mm holes in two next plates. The next two plates wil not have a hole.
Step 4: Rods
Take rods and add nuts and washers to their bottom.
Step 5: Base
Make a base by inserting the rods into the bottom plate.
Step 6: Add More Layers
Add spacers to the base, then add next plate, then the spacers and so on. Repeat this proces until you'll have four layers.
Step 7: Insert DS18B20
As I said before, the two bottom plates have 3mm hole in center and next two plates have 6mm hole in center. Now, take the DS18B20, insert it into the top hole and pull it all the way through all the holes.
Step 8: Add More Layers Volume II
Add two more layers like before.
Step 9: Top and Wall Bracket
At the end we have to add the nuts on top to hold everything together. Also, we need take the wall bracket and mound it on the top.
Step 10: Done
Congratulations. You have competed your solar radiation shield. Now you can use it as a part of the "Arduino Weathercloud Weather Station" or as a part of your own weather station.
