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 (colors vary)

6. Pressure sensor

7. Relative humidity sensor

8. Temperature sensor

9. Capacitor (unpolarized)

10. Resistor (unpolarized)

11. Easy-Plug IO adapter board for cable to flight computer

12. Right angle header for cable

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. Cut red, green, and 3 more (colors vary). Strip both ends of each wire ¼ inch.

20. Twist exposed ends of wires then tin them

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

22. Repeat with other wires – use green/black for ground (GND) and red for +5 volts

23. Slide on shrink-wrap before proceeding. Use blue shrink-wrap provided at table.

24. Make 5-wire cable, using strain relief. Red +5 volts, green GND, 3 signal wires.

25. Finish cable by adding the 1 x 5 right angle header. Be quick – don’t melt it!

26. Completed Weather Station (with earlier cable termination style); ready for testing)
