Hall magnetic field sensor A3141 With this small Hall magnetic field sensor, you can detect magnetic fields with the help of the sensor's digital output and the integrated status LED. The transistor switches through when the module is positioned in a magnetic field. This can then be read out at the signal output as a voltage value; the signal output is set to low in a magnetic field. Other systems can also be used with code adaptations. The sensor can be permanently soldered, but can also be used on a breadboard. The module can be permanently soldered or used on a breadboard. https://elecena.pl/product/18403234/sen-ky003hms-developer-boards-hall-magnetic-field-sensor-a3144 2021-05-08 https://elecena.pl/product/18403234/sen-ky003hms-developer-boards-hall-magnetic-field-sensor-a3144 2025-02-08
