Hall Effect Sensor: A Hall sensor is a device which can detect the presence of a magnet based on its polarity.It is a transducer which generates a signal according to magnetic field present near it.

Hall Effect sensor is a small-scale microelectromechanical systems (MEMS) device for detecting and measuring magnetic fields. These sensors can detect changes in a magnetic field like flux, strength, ...

Magnetic field (Gauss) meter circuit design. The principle of the present meter is shown in the block diagram in Figure 1. The induction coil used to detect the magnetic field is represented by an ...

Autozero circuit that allows the user to automatically adjust the zero-point virtual ground terminal of the scope with the ...

This paper proposes an eddy current testing (ECT) probe with high-resolution tunneling magnetoresistance (TMR) array sensors for vector magnetic field measurement. The probe consists of two printed ...

A Hall effect sensor is an electronic device that is designed to detect the Hall effect, and convert its findings into electronic data, either to switch a circuit on and off, provide a measurement of ...

The magnetic field distribution of magnetostrictive composites of magnetic circuits significantly affects the measurement range of magnetostrictive current sensors. A novel technique to extend the ...

Using this design framework, they built an energy management circuit for an off-the-shelf temperature sensor. The device harvests magnetic field energy and uses it to continually sample ...
