Hall Effect Sensor - Overview

Hall effect sensor

The Hall effect sensor circuit board is a high-precision sensor that measures the presence of a magnetic field using its digital output version and quantifies the magnetic field’s strength with the analog version of the breakout board. This sensor is an excellent option for determining the presence, position, and proximity of magnetized objects. It also comes in a version with I2C communication featuring a default address of 0x30, and it is designed for seamless Qwiic (formerly easyC) connectivity—eliminating the need for soldering.
