Barographs

A barograph records a graph of some atmospheric pressure and uses an aneroid barometer mechanism to move a needle on a smoked foil or to move a pen upon paper, both of which are attached to a drum moved by clockwork.[12]

More unusual barometers

The Galaxy Nexus has a built-in barometer[13]
There are many other more unusual types of barometer. From variations on the storm barometer, such as the Collins Patent Table Barometer, to more traditional looking designs such as Hooke's Otheometer and the Ross Sympiesometer. Some, such as the Shark Oil barometer,[14] work only in a certain temperature range, achieved in warmer climates
A barometer can also be found in smartphones such as the Samsung Galaxy Nexus smartphone,[15] which is included to provide a faster GPS lock.[16]
