10pcs OH137 OH 137 Linear Hall Effect Magnetic Unipolar Sensor Switch IC Arduino

Description

Description:
Hall-effect sensors are commonly used for measuring the speed of rotating assemblies where a magnet on the assembly alternately makes and breaks magnetic contact with the sensor as the assembly rotates.  They can also be used for applications such as determining when a door has been opened, position sensing and detecting the magnetic field created by current flow in a wire.
