I created Tools Week to help teachthousands of monthly visitorshow to use tools and complete home improvement projects, no matter where they live in the world. The hall effect sensor is a type of magnetic sensor which can be used for detecting the strength and direction of a magnetic field produced from a permanent magnet or an electromagnet with its output varying in proportion to the strength of the magnetic field being detected. The output signal for linear (analogue) sensors is taken directly from the output of the operational amplifier with the output voltage being directly proportional to the magnetic field passing through the Hall sensor. It offers the advantage of unity gain buffers that can be switched in and out to allow measuring high resistances by buffering the sample resistance from the meter. Hall Effect Sensors can be used to measure linear current flow as the current flowing through the conductor (wire) being measured generates a magnetic field. Understanding that a digital voltmeter will only show an average reading of fast changing signals, is the key to understanding how to test these types of sensors without a lab scope. As a result, the following materials are especially suitable for Hall-effect sensors: 1 gallium arsenide (GaAs), 2 indium arsenide (InAs), 3 indium phosphide (InP), 4 indium antimonide (InSb), 5 graphene.
