Sensor -Services Overview

Key Concepts -and Terms

Sensor: A sensor is a hardware measuring device connected to the Symbian -device, which measures a physical quantity in its immediate vicinity and converts -that quantity into small sets of numeric digital values.
Sensor Subsystem (SSY): Sensor Subsystems are plug-ins that connect the sensor hardware with -the sensor server.

Architecture - -Sensor Services Architecture - -

The Sensor Services collection consists of the following components:

Sensor Framework, which provides sensor server and plug-in interfaces -for adding any new sensor plug-in as required. The framework also provides -sensor channel APIs for creating a medium (sensor channel) of exchange between -the client applications and the sensor hardware. The sensor plug-ins retrieve -data from sensor hardware (through sensor channels) and enable the client -applications to use the data for specific requirements.
Data Compensator, which uses data provided by the sensor plug-ins -to correct the sensor axis data based on the current orientation of the Symbian -device. This data can be used by the client applications to display the pages -in portrait or landscape views.

Typical Uses

Using Sensor -Channel APIs.
Compensating -Sensor Data for Display Orientation
