SCP1000 Static Barometer

For delta-height measurements:

~9cm accuracy (1.8Hz sr) or

~20cm accuracy (9Hz sr)Low power (~25uA)

Breakboard: ~20.00

Will need additional processor board toperform the interface (if Thales systems

interface cannot provide it somehow)

Basic logger testing costs:~90.00

Capable to log data directly from thebarometer board, for evaluation

purpouses.
