描述
Grove – Hall Sensor 霍爾感測器
霍爾傳感器是基於霍爾效應的，霍爾效應是橫跨電導體的橫向於導體中的電流和垂直於電流的磁場的電壓差的產生。這個Grove有一個連續的時間開關。當與霍爾傳感器垂直的磁場（南極）超過操作點閾值BOP時，這些設備的輸出開關變低（接通），當磁場消失時，這些設備開關為高（關閉）。樹枝可以用來測量轉速。
特徵
- Grove兼容接口
- 400ns的過渡期為上升和下降。
- 連續時間霍爾效應傳感器
- 反向電池保護

Resources
The Hall Sensor measures the Hall Effect, which is a production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor as well as a magnetic field perpendicular to the current. The output of the continuous-time switch Hall sensor on this Twig switches low and turns on when a magnetic field (south polarity) perpendicular to the Hall sensor exceeds the BOP threshold, and it switches high and turn on when the magnetic field disappears.
