Hall Effect Sensor Distance

Hall effect sensor can be used for contact less precise measurement of position.

Hall effect sensor distance.

Hall effect sensor reacts to magnetic array with change of its output analogue voltage. When a magnet approaches the face of the sensor the output voltage will increase or decrease depending on which side of the magnet you are using. Static characteristic is measured for both polarity of permanent magnet which has been used as source of magnetic array. The third hall effect sensor distance a 324 reads the magnetic field gradually.

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. Hall effect sensors are used for proximity sensing positioning speed detection and current sensing applications. 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. I think hall effect sensors can do that.

General features of hall effect based sensing devices are. 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. When no magnetic field is sensed this sensor will output half of the source voltage 2 5v. I m not even sure that the gauss rating is relevant to the question.

Paper deals with hall effect sensors used for position measurement. Its output voltage is directly proportional to the magnetic field strength through it. 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. 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.

I want to use a this hall effect sensor to detect the presence of magnet. A hall effect sensor is a device that is used to measure the magnitude of a magnetic field. 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.
