霍尔传感器(Hall Effect Sensor)是根据霍尔效应制作的一种磁场传感器,当恒定电流通过内部的霍尔半导体片时,将在垂直方向产生电位差即霍尔电压。这个霍尔电压随磁场强度的变化而变化,磁场越强,电压越高,磁场越弱,电压越低。虽然霍尔电压很小,通常 ...
Allegro的ACS712电流传感器是一款基于霍尔效应的效应的电流传感器。 霍尔效应传感器是换能器类型的组件,可以将磁信号转换为电信号以进行后续的电子电路处理。通常,电流传感器使用霍尔效应将电流输入转换为电压输出。在霍尔效应中,来自电流的电子流过 ...
The title says it all – this article describes a microcontroller-compatible current sensor module you can build yourself, using an inexpensive 8-pin chip as an ‘active shunt’ for measuring ac/dc ...
