All Pebble watches contain a collection of sensors than can be used as input
|
||
|
|
devices for apps. Available sensors include four buttons, an accelerometer, and
|
||
|
|
a magnetometer (accessible via the ``CompassService`` API). In addition, the
|
||
|
|
Basalt and Chalk platforms also include a microphone (accessible via the
|
||
|
|
``Dictation`` API) and access to Pebble Health data sets. Read
|
||
|
|
{% guide_link tools-and-resources/hardware-information %} for more information
|
||
|
|
on sensor availability per platform.
|
||
|
|
|
||
|
|
While providing more interactivity, excessive regular use of these sensors will
|
||
|
|
stop the watch's CPU from sleeping and result in faster battery drain, so use
|
||
|
|
them sparingly. An alternative to constantly reading accelerometer data is to
|
||
|
|
obtain data in batches, allowing sleeping periods in between. Read
|
||
|
|
{% guide_link best-practices/conserving-battery-life %} for more information.
