SENSOR_CATEGORY_LOCATION

The SENSOR_CATEGORY_LOCATION category contains sensors that provide geographic location information.

Platform-defined Sensor Types

This category includes the following platform-defined sensor types.

Sensor typeMeaning

SENSOR_TYPE_LOCATION_BROADCAST

Sensors that transmit location information through transmissions such as television or radio frequencies.

Lookup sensors, such as those that provide information based on the user's IP address.

SENSOR_TYPE_LOCATION_OTHER

Other location sensors.

SENSOR_TYPE_LOCATION_STATIC

Fixed-location sensors, such as those that use preset, user-provided information.

SENSOR_TYPE_LOCATION_TRIANGULATION

Triangulation sensors, such as those that determine the current location based on cellular phone tower proximities.
