From the project
Hardware design, BOM, gerbers and 3D files for Hall-effect-sensor-breakout-with-analog-output-&-qwiic designed by Soldered Electronics.
The Hall effect sensor breakout with analog output is a versatile and reliable sensor module designed to detect and measure magnetic fields. It utilizes the Hall effect principle, where the presence of a magnetic field induces a voltage proportional to the strength and direction of the field.
This sensor module features an analog output, which provides a continuous voltage signal that varies in response to changes in the magnetic field. The analog output allows for precise and real-time monitoring of magnetic field strength. It is commonly used in applications such as position sensing…
