Linear Hall Effect Sensor

Linear hall effect ics are magnetic sensor devices designed to respond to magnetic fields to produce a proportionate amount of electrical output.

Linear hall effect sensor. A hall effect sensor is a device that is used to measure the magnitude of a magnetic field. Hall effect sensors can be viewed as linear transducers. The sensors detect the magnetic field and generate an very small analog output signal proportional to the magnetic field.

Its output voltage is directly proportional to the magnetic field strength through it. It thus becomes useful for measuring the strength of magnetic fields and in applications that require an output switched through magnetic triggers. Akm offers 4 levels of sensitivities in the smt sop and sip version. Applications of hall effect sensor.

The output signal for linear analogue sensors is taken directly from the output of the operational amplifier with the output voltage being directly proportional to the magnetic field passing through the hall sensor. It s compatible with popular electronics platforms like arduino raspberry pi esp8266 and teensy. Akm asahi linear hall effect ic magnetic sensors consist of a hall element and an amplifer in a package. Depending on the magnetic field the output does not have a discrete switching state but provides a signal proportional to the magnetic field strength.

The ky 024 module consists of a 49e linear hall effect sensor a lm393 dual differential comparator a potentiomenter two leds and six resistors. Linear hall sensors overview linear hall sensor families linear hall sensors differ from the switches as follows. Diodes linear hall sensors provide high linearity outputs whose voltage is proportional to the applied magnetic flux density. Hall effect sensors are available with either linear or digital outputs.

Whether detecting the linear travel of a magnet or the angular position of a rotary application linear hall effect sensors provide contactless accurate position sensing. To process the sensor s output these require a linear circuit that can provide a constant driving current to the sensors and also amplifies the output signal.
