Mounting Tips
Let It Breathe: Air Holes in Containers
AltimeterTwo uses an atmospheric pressure sensor to detect altitude, so
it needs to be exposed to outside air pressure. If you put it in a container,
or if your rocket payload compartment is airtight, be sure to add a few
holes to allow air to escape at altitude.
The larger the airspace is in your model, the larger the holes should be.
Remember: if your model can rapidly gain or lose altitude, your vent holes
need to allow air to rapidly enter and exit the enclosure.
Avoid Really Strong Airow
Airow near the nosecone of the rocket can create pressure waves that
can sometimes confuse AltimeterTwo and result in odd readings.
Specialized Mounting Accessories
Check the Jolly Logic website for mounting accessories such as the Snap
Mount. The Snap Mount can be taped, screwed, or attached with Velcro
TM
to hold it in place. AltimeterTwo can then be quickly snapped in place.
If you mount your AltimeterTwo with your parachute, try to ensure that
the altimeter is protected from direct contact with ejection gases.
