Description
This hall effect unit has three A3144E hall sensor switches, improved by 74HC series gate integrated circuits for reliable signal processing. This unit provides a low-level signal when the south pole of a magnet is near the front of the sensor or the north pole is close to the back, lighting up the internal LED indicator for visual feedback.
It is ideal for various uses, including door sensor alarms, proximity detection, and rotation speed measurement. With the front side designed to detect the north pole and output a low level when sensing the south pole of a magnetic field, it provides easy magnetic sensing for a range of projects.
