Radiation Shield For Weather Station Temperature/Humidity

thingiverse

Weather Station Radiation Shield for Air Temperature and Humidity Measurement: A Versatile and Robust Solution. Includes Adapters for Multiple Sensors, Such as: 1) HTU21D-F Breakout from Adafruit, www.adafruit.com/product/1899 2) SHT15 Breakout from SparkFun, https://www.sparkfun.com/products/13683 3) AM2315 Sensor from Adafruit, https://www.adafruit.com/products/1293 4) HTM2500LF from Meas-spec and Future Electronics, http://www.meas-spec.com/product/t_product.aspx?id=2466 & http://www.futureelectronics.com/en/technologies/semiconductors/analog/sensors/humidity-dew/Pages/9758327-HTM2500LF.aspx For Long-Term Deployments, Apply UV-Resistant Spray to Printed Parts. Recommended Coating: Clear Krylon Fusion. http://www.amazon.com/Krylon-2444-Fusion-Plastic-Clear/dp/B001TNMWBM Mounting Brackets Are Included for Easy Attachment to 1-Inch Pipe Using 1.5 Inch U-Bolts. Post Production Photos Provide a Clear Guide to Assembly. Example Arduino Code for Logging HTU21DF Sensor is Available at https://gist.github.com/jaymham/a2862e4de19121c13742 & https://gist.github.com/jaymham/95cb4a0ec77171eb3836.

For Minimum Solar Radiation Absorption, Use Bright White Ultimachine ABS. Some Sources May Require Painting With Rust-Oleum Painters Touch 2X Ultracover in Gloss White. Post-Printing Instructions: Tap Top Section for 10-24 Threads Install All-Thread for Vertical Support, 4 or 4 1/8 Inches Long Each, 10-24 Thread Install Base Plate with 10-24 Nuts. Ensure M5 or 10-24 Set Screw is Secured Before Mounting Add Mounting Bracket, with Additional 10-24 Nuts. Consider Jam Nuts for Added Security Clean Solder Pads on HTU Sensor with Alcohol and Apply 5-Min Epoxy Only to Solder Joints. Coat the Signal Wire with Round 4-Conductor Solid-Core Telephone Wire. (Recommended Product: RCA 100' 4-Wire Round Station Wire Cord - Almond, Lowes #82473) Long-Term Weather Exposure Has Resulted in Corrosion and Residue on Solder Pads/Joints. To Prevent Further Damage, Clean the Solder Pads with Alcohol and Apply Clear Epoxy Sparingly. As an Alternative, Coat the Entire Board with Silicon Conformal Coating. Ensure Not to Get Any Coating on the White Plastic PTFE Filter on the RH Sensor.
