Hall effect current sensor with internal integrated circuit amplifier. When this charged conductor comes in contact with the magnetic field which is in a perpendicular direction to the motion of electrons, the electrons get deflected. If the quantity (parameter) to be sensed incorporates or can incorporate a magnetic field, a Hall sensor will perform the task. Magnet-based sensors such as reed switches and Hall effect sensors react to the presence of a magnetic field. Fig : A wheel containing two magnets passing by a Hall effect sensor. Magnetoresistors are used to measure the direct magnetic field or those effects related to the measurement of other quantities by means of a magnetic field variation. There are also other Hall effect sensor applications where a contactless switch is needed, such as electric air guns, go-kart speed controls, and on the triggers of electro-pneumatic paintball guns. Hall effect sensors and reed switches are indeed different things. A Hall-effect sensor varies its output voltage in response to a magnetic field. Speed Sensor Type.
