The M5Stack Hall Effect Unit is a module with three Hall sensors A3144E. It reacts to the proximity of a magnet with the S field from the top or the N field from the bottom of the housing. Using signals from three sensors connected to logic with AND gates makes the output signal very stable. At the output, the user has at his disposal a digital signal that is led out on the Grove connector. The module is supplied with 5 V, has a built-in 3.3 V stabilizer and a diode indicating the output status. The kit can be widely used in applications such as door alarm sensors, proximity sensors, or for speed measurement. Full documentation is available on the product page.
