SMAccelerometerSensor Class Reference

Inherits from	SMSensor : NSObject
Declared in	SMAccelerometerSensor.h SMAccelerometerSensor.m

Overview

A sensor for reading accelerometer information from the device

The data returned from this sensor is in the form of the SM3DMotionSensorData class.

Other Methods

`– initWithSenseCallback:timeInterval:`

Initialises the accelerometer sensor with specified callback and repeat time interval

- (id)initWithSenseCallback:(SenseCallback)callback timeInterval:(NSTimeInterval)secs

Parameters

`callback`	callback for data
`secs`	seconds between sensing

Return Value

Accelerometer sensor

Discussion
