1. Building a Weather Station for a Near-Space Payload AEM 1905: Spaceflight with Ballooning University of Minnesota

2. Weather Station kit and instructions

3. Parts in Weather Station kit

4. Printed Circuit Board (PCB)

5. Wires for sensor cabling

6. Pressure sensor

7. Relative humidity sensor

8. Temperature sensor

9. Capacitor (unpolarized)

10. Resistor (unpolarized)

11. 3 x 3 pin male header for sensor cable

12. Heat-shrink tubing (AKA shrink-wrap)

13. Solder resistor in place; snip all excess leads

14. Solder the capacitor in place

15. Insert relative humidity sensor, making sure that the open part faces capacitor

16. Avoid solder bridges on closely-spaced pins of the relative humidity sensor

17. Insert the temp sensor, watching polarity

18. Insert pressure sensor, right way around

19. Strip both ends of each wire, exposing ¼ inch length of the bare metal

20. Insert one wire through large hole then bend it over and solder – for strain relief

21. Repeat with other 4 wires – use black for ground and red for +5 volts (at least)

22. Insert 3 x 3 header into a female receptacle, like that in a BalloonSat Easy computer

23. Orient 3 x 3 pin header next to the figure to identify which pins to solder wires to

24. Tin the 5 pins – add a bit of solder quickly

25. Twist exposed ends of wires then tin them

26. Slide on shrink-wrap before proceeding. Use blue shrink-wrap, not stuff in kit.

27. Use Helping Hands to hold wire up to pin

28. Solder 5 wires to pins, minimizing diameter

29. Slide shrink-wrap over solder joints once all wires have been soldered

30. Shrink with heat gun while still plugged in, then remove cable from receptacle

31. Completed Weather Station; ready to be plugged into a flight computer
