How It Works
The Hall Effect sensor detects changes in the magnetic field near the sensing element. When the magnetic field reaches the configured threshold, the module’s LM393 comparator changes its output state.
The output can then be connected to a digital input of a microcontroller to detect events such as the presence of a magnet, movement, rotation, or position change.
