Mayf, 5 volt feed is what's needed, and this will aslo keep the output
limited to a max of 5v of course to protect the input of your logging device.
If a 5 volt source is not available... the BMP and MAP sensors work fine fed
off a standard 5volt regulator from radio shack(#276-1770) that's being
powered by your regular battery source, as does any of these sensors that use
less then 1amp(and this regulator is very forgiving of input voltage surges
up to about 30volts).
