This module measures magnetic fields and gives a signal at an adjustable switching point. The magnetic switch works at 3.3V and 5V, whereby the sensitivity can be adjusted with the potentiometer. At maximum sensitivity, a magnetic field at a distance of 1.5 m from a device can be detected. https://elecena.pl/product/27738282/opencircuit-magnetic-switch-module 2025-01-22 https://elecena.pl/product/27738282/opencircuit-magnetic-switch-module 2026-02-20 https://elecena.pl/product/27738282/opencircuit-magnetic-switch-module 2026-04-14 https://elecena.pl/product/27738282/opencircuit-magnetic-switch-module 2026-04-25
