Hall Effect Sensor Output Voltage

The voltage signal produced by the sensor depends on the speed of the trigger wheel and the number of turns in the coil so an output voltage could be expected between 1v and 2v during the engine.

Hall effect sensor output voltage. With a lab scope a 2 wire hall effect abs sensor signal voltage is measured with the wheel turned by hand. The output of the comparator can drive the led with suitable series resistor. To help determining whether the 2 wire hall effect abs sensor is functioning correctly different deviations from the example signal are mentioned along with possible causes. Hall effect sensors are used for proximity sensing positioning speed detection and current sensing applications.

Set one input of the comparator to a reference level of say 350 mv. Consider the diagram below. What the comparator will be showing is if the hall sensor voltage is above or below the reference voltage. Frequently a hall sensor is combined with threshold detection so that it acts as and is.

When the magnetic flux density around the sensor exceeds a certain pre set threshold the sensor detects it and generates an output voltage called the hall voltage v h. Hall effect voltage sensor transducer hall voltage sensor transducers voltage sensor tranducer.

A hall effect sensor or simply hall sensor is a device to measure the magnitude of a magnetic field its output voltage is directly proportional to the magnetic field strength through it. The output signal from a hall effect sensor is the function of magnetic field density around the device. 25ma 15vdc 0 5 25 c 85 c. B field response of the drv5053 when no magnet is present b 0 the output.

The hall sensor output feeds into the other input of the comparator.
