Web7 de jan. de 2024 · Hall effect sensors, or DC current sensors, are capable of measuring both AC and DC current. Hall effect sensors consist of a core, a Hall effect device, and signal conditioning circuitry. They operate based on the Hall Effect. The Hall Effect is a phenomenon discovered by Edwin Hall in 1879. When current moves through a … WebA Hall sensor in its most basic form is an analog integrated circuit. It consists of a Hall plate that outputs a "transverse" voltage based on the intensity of a magnetic field - polarity is dependant on magnetic polarity. It also consists of a high gain differential amplifier because the generated voltage is small.
