Abstract

The invention discloses a Hall sensor and sensor device. The Hall sensor and sensor device comprises the components of a circuit board, a Hall semiconductor plate, measuring terminals, permanent magnet blocks, an amplifying circuit, a signal converting module and an external display device. The Hall semiconductor plate is fixedly arranged on the circuit board. The measuring terminals are respectively connected with the front end and the back end of the Hall semiconductor plate. The permanent magnet blocks are fixedly connected with the surface of the Hall semiconductor plate. The amplifying circuit is arranged on the circuit board. The amplifying circuit is connected with the left side and the right side of the Hall semiconductor plate. The signal converting module is mounted on the circuit board. The external display device is connected with the signal converting module through a signal wire. The permanent magnet blocks are plate-shaped and furthermore two permanent magnet blocks are arranged. The permanent magnet blocks are respectively connected with the front side and the back side of the Hall semiconductor plate fixedly. The polarities of two adjacent surfaces of the two permanent magnet blocks are opposite from each other. The Hall sensor and sensor device has advantages of simple structure, reasonable design, high convenience in use, high use effect, easy popularization, etc.

Description

technical field [0001] The invention relates to the technical field of sensor equipment, in particular to a Hall sensor and a sensor device. Background technique [0002] The Hall sensor is a magnetic field sensor made according to the Hall effect. The Hall effect is a kind of magnetoelectric effect, which was discovered by Hall in 1879 when he was studying the conductive mechanism of metals. Later, it was found that semiconductors and conductive fluids also have this effect, and the Hall effect of semiconductors is much stronger than that of metals. Various Hall elements made of this phenomenon are widely used in industrial automation technology, detection technology and information processing, etc. aspect. The Hall effect is a basic method for studying the properties of semiconductor materials. The Hall coefficient measured by the Hall effect experiment can determine important parameters such as the conductivity type, carrier concentration, and carrier mobility of semic...
