Hall Effect Speed Sensor Circuit

Frequently a hall sensor is combined with threshold detection so that it acts as and is called a.

Hall effect speed sensor circuit.

Hall effect sensors are used for proximity sensing positioning speed detection and current sensing applications. Hall sensor reacts to magnetic field and changes its output depends on the polarity of magnet and magnetic field strength still now used in many applications by using this types of sensor we can create multipurpose hall effect sensor circuit. 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. Here taken hall effect sensor drv5013 from texas instruments it is a digital latch hall effect sensor and operates with wide voltage ranges 2 5 to 38v.

The simple circuit diagram can be seen below. 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 hall effect sensor explained above can be quickly configured through a few external parts for converting magnetic field into electrical toggling pulses for controlling a load. Its output voltage is directly proportional to the magnetic field strength through it.

This ic can detect magnetic fields. A hall effect sensor is a device that is used to measure the magnitude of a magnetic field. The specially designed ic integrated circuit and a permanent magnet are sealed in rugged probe type packages the flux density of the permanent magnet alters when approached by ferrous metal. We will then connect this ic to an arduino so that we the arduino can read the voltage output by the a1302 and we can display the readings to the computer screen.
