【应用】小体积超低功耗霍尔开关Si7201在智能水表中的应用
物联网带动了水表集抄的升级，很好解决以往一直困扰着抄表难，缴费难。物联网水表是在老式的机械水表基础上增加了电子控制和传输、集抄表、缴费、控制为一体，大大便捷了工作和生活。
针对老式的机械水表改造融合升级问题，本方案基于超高性价比使用SILICON LABS的Si7201霍尔开关设计的，使用时使用磁性物体开启，通过在机表上一个随着水的流动而转动的圆盘安装一个磁铁，霍尔开关放于圆盘上方，通过采集霍尔开关波形变化来计算水的流量，达到水表计量的目的。并且具有低功耗、低成本，电路设计简单等优点。非常方便，框图如下：

Silicon Labs SOT23-3封装的低功耗霍尔开关Si7201主要优势如下：
1、小封装SOT23-3，便于产品体积的缩小。
2、1.8~3.6V供电范围，无需再额外增加电源转换器。
3、400nA超低运行功耗，为智能水表提供最长的待机时间。
4、5Hz采样速率，响应迅速，提升用户产品体验。
5、应用简单，检测到磁性物体后，及可以在输出引脚输出高电平，无需编程。
Silicon Labs的超低功耗霍尔开关Si7201在低功耗上已经远超普通的霍尔器件厂家，可以说是该方案的最佳选择。
