sensor out of direct sunlight.
The barometric sensor sampling ports must be able to
- "breathe", both by not being covered by foam or tape or other
- materials that might directly block the hole on the top of the
- sensor, and also by having a suitable static vent to outside
- air.

As with all other rocketry electronics, Altus Metrum
altimeters must be protected from exposure to corrosive motor
