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.
