Hall Effect Sensor Distance

This paper introduces hall effect technology and then explores how it has been applied in particular differentiating between the primary types of hall sensor ics and the highly differentiated range of sensing behaviors they can support.

Hall effect sensor distance.

I want distances ranging from 10cm 1m 4 40 inches and a hall effect sensor can t do that right. General features of hall effect based sensing devices are. Paper deals with hall effect sensors used for position measurement. Hall effect sensors are used for proximity sensing positioning speed detection and current sensing applications.

The sensor should be able to measure the space around it ie the sensor measures distance not linearly like an ir sensor or an ultra sonic sensor but spherically. Hall effect sensors consist basically of a thin piece of rectangular p type semiconductor material such as gallium arsenide gaas indium antimonide insb or indium arsenide inas passing a continuous current through itself. The third hall effect sensor distance a 324 reads the magnetic field gradually. When no magnetic field is sensed this sensor will output half of the source voltage 2 5v.

Static characteristic is measured for both polarity of permanent magnet which has been used as source of magnetic array. Its output voltage is directly proportional to the magnetic field strength through it. I want to use a this hall effect sensor to detect the presence of magnet. I m not even sure that the gauss rating is relevant to the question.

Hall effect sensor can be used for contact less precise measurement of position. Hall effect sensor reacts to magnetic array with change of its output analogue voltage. True solid state long life 30 billion operations in a continuing keyboard module test program high speed operation over 100 khz possible operates with stationary input zero speed no moving parts logic compatible input and output broad temperature range 40 to 150 c highly repeatable operation. Magnet sensor hall effect device position sensing device.

Frequently a hall sensor is combined with threshold detection so that it acts as and is called a. When the device is placed within a magnetic field the magnetic flux lines exert a force on the semiconductor material which deflects the charge carriers electrons and. I m pretty sure i understand how to use the hall effect sensor but i m not sure how to calculate the distance the sensor can detect a magnet of a given gauss.
