iPhone中的加速度计范围 [英] accelerometer range in iPhone

问题描述

我已经在我的应用程序中实现了以下方法.

i have implemented following method in my application.

- (void)accelerometer:(UIAccelerometer *)acel didAccelerate:(UIAcceleration *)aceler {
if (fabsf(aceler.x) > 1.5 || fabsf(aceler.y) > 1.5 || fabsf(aceler.z) > 1.5 || fabsf(aceler.x) < -1.5 || fabsf(aceler.y) < -1.5 || fabsf(aceler.z) < -1.5 )
{
    self.navigationItem.rightBarButtonItem=nil;
    [self showImage:nil];
}

}

=>我很想知道"aceler.x的范围".

=> I am eager to know " The range of aceler.x ".

即aceler.x/y/z的最大值是多少

i.e. what would be the maximum value of aceler.x / y / z

最低收费是多少? (我认为应该为零)

Same way the minimum ? ( I think, it should be zero )

预先感谢您的帮助.

推荐答案

快速搜索显示iPhone使用的是页面中，我遇到了，提到输出固定在2.37G，因此看来它们使用2G模式或仅支持2G的LIS302.

A quick search shows that the iPhone uses a LIS302 accelerometer. The datasheet I linked shows +-2G or +-8G. There is also a version of the LIS302 that only does +-2G. From another page I came across, mentions the output pegging out at 2.37G, so it appears they use the 2G mode or the LIS302 that only supports 2G.
