【技术】基于霍尔效应磁传感器实现无接触式旋钮开关原理
旋钮开关在智能家居的调光旋钮，汽车中控台的旋钮，档位旋钮等等。常用的方案有电位器式旋钮开关，这是一种接触式的实现方法，有机械磨损，影响使用寿命。SILICON LABS针对开/关/位置侦测等应用，推出霍尔效应磁传感器（HallEffectSensor）系列产品--Si721x，进一步为各种汽车、工业或物联网（IoT）产品的旋钮/开关/位置应用设计提供了无接触式的绝佳解决方案。
图1：汽车上使用的开关旋钮
无接触式旋钮开关实现原理如下：
霍尔传感器有很多种类，简单的数字输出型霍尔只提供粗略的位置，例如接近或远离磁铁。如果使用模拟输出或I2C数字输出的线性霍尔Si721x，可以通过设置霍尔传感器和磁铁来建立非常灵敏的位置指示器；因为磁场强度随位置而变化，这样就可以采用高精度的线性霍尔传感器实现精确的位置测量。当场从正到负时，位置可以非常精确地测量。在下面的例子中，传感器位于磁铁中心正下方8毫米，然后左右移动得到的一个位置与磁场强度的曲线。如下图所示：
图2：霍尔传感器在不同的位置检测到磁场强度
在位置检测的基础上，可以通过设置霍尔传感器来检测磁铁周围的磁场变化来建立旋转角度的测量。使用两个霍尔传感器成90°摆放，使用两个磁铁在周围旋转，使磁场变化近似90度正交，这样会使得角度计算更为简单。图3是霍尔传感器与磁铁的位置关系：
说明：左图的U1和U2是霍尔传感器，右图的中心孔边上的两个金属色的物体是磁铁。
图3：霍尔传感器与磁铁的位置关系
在这种位置关系摆放下，通过旋转轮盘，让两个磁铁围绕着霍尔传感器旋转，就可以得到两条曲线，精确的计算角度，如图4所示。每旋转1度角度，磁场变化大约是0.1mT。如果使用的传感器噪声为30uTRMS，那么角度的测量分辨率可以达到约0.3度。增加平均值算法可以让分辨率提高。实现高精度的角度测量，应对无接触式旋钮的应用非常完美。

借助SiliconLabs成熟的CMOS设计技术，Si721x产品系列融入数字信号处理，为温度和失调漂移提供精密补偿。与现有霍尔效应传感器相比，Si721x产品系列具有行业领先的灵敏度和低噪声，使传感器能够在较大气隙和较小磁体条件下使用。在汽车应用方面，Si721x产品系列符合AEC-Q100标准。同时具备更低的睡眠电流50nA，可广泛应用于电池供电产品。
