Hinge motion is commonly seen when monitoring door and lid positions, such as when detecting the screen position on a laptop. A simple hands-on tool to test the hinge function manually is available using the HALL-HINGE-EVM, which features a 3D printed assembly that includes magnet and sensor adjustment and a protractor with 1 degree intervals.
To simulate hinge motion, select "Hinge" from the top-menu.
The resulting prompt appears as shown in #GUID-84D91191-432B-44FD-9F23-BC080A3775DC
Magnet travel for this type of motion is described by the magnet rotating by some angular distance about the X-axis. This is normally setup by placing the sensor and magnet at some horizontal displacement from the hinge in the Y-direction. Vertical offset from the hinge may be set in the Z-direction.
The angular distance is entered by the user in the field marked "Arc Length" in the Magnet Motion section. An arc length of 360 produces a complete circular rotation about the X-axis.
