What Is a Hall Effect Sensor?

A Hall effect sensor detects the presence of a magnetic field and converts it into an electrical signal. The 3144 sensor is a digital Hall effect sensor that provides a clean ON/OFF output when exposed to a magnetic field.

How the 3144 Hall Effect Sensor Works

• When no magnet is near, the output remains HIGH

• When a magnetic field is detected, the output switches LOW

• Once the magnet is removed, the sensor resets automatically

This makes it ideal for proximity detection and speed sensing.
