摘要: A magnetic sensor includes a board, a magnetoresistance element group including first and second magnetoresistance elements disposed on the board, and a magnet group including a first magnet corresponding to the first magnetoresistance element and a second magnet corresponding to the second magnetoresistance element. This magnetic sensor can have a small size and high accuracy.

摘要: A magnetic sensor includes a magneto-resistive element, a Hall element, and a detection circuit that receives a signal from the magneto-resistive element and a signal from the Hall element input thereto. The detection circuit includes an output terminal and an interrupt generation unit. The output terminal outputs, to the outside as an output signal, a signal obtained by performing to the signal input from the magneto-resistive element, at least one processing selected from amplification, analog-to-digital conversion, offset correction, and temperature-characteristics correction. The interrupt generation unit outputs an interrupt signal when the signal input from the Hall element is larger than a predetermined threshold. The magnetic sensor is high accurate and highly reliable.

摘要: A magnetic sensor includes a first magnetoresistive element that detects a magnetic field along a first detection axis, a second magnetoresistive element that detects a magnetic field along a second detection axis inclining at an angle of 45 degrees with respect to the first detection axis, a first Hall element that detects a magnetic field along a third detection axis, and a second Hall element that detects a magnetic field along a fourth detection axis perpendicular to the third detection axis. This magnetic sensor has both characteristics of the Hall elements and characteristics of the magnetoresistive elements, and has high accuracy and a small size.
