8. Component Highlight
Hall Effect Sensors

9. Hall Effect Sensor
A Hall-Effect Sensor is a type of transducer that creates an output voltage in the presence of a magnetic field

10. Hall Effect Sensor Uses: Magnetic Field Sensing
Placed inside a DC current transformer, the magnitude of the magnetic field can be measured, and the current calculated
Position Sensing
Can be used to sense the presence of a magnetic object, with many applications
