A3144 Hall Effect Magnetic Sensor Module
Integrate reliable, frictionless magnetic velocity and position tracking into your machinery with the premium A3144 Hall Effect Sensor Module. Explicitly engineered for non-contact proximity detection, this high-performance sensor board houses a rugged A3144 unipolar Hall effect integrated circuit paired with an LM393 voltage comparator layout. When a magnetic south pole enters its localized tracking threshold, the circuit instantly senses the flux alteration and flips its state without mechanical bounce or friction wear. The breakout module incorporates an onboard high-precision potentiometer to tune the switching sensitivity along with a clean digital output (DO) pin that interfaces seamlessly with microcontroller GPIO inputs. It serves as the definitive hardware component choice for constructing digital tachometers, electric vehicle wheel speed logs, non-contact smart door alarms, conveyor belt unit counters, and BLDC motor timing grids.

The A3144 Hall Effect Sensor Module is a digital magnetic switch sensor used to detect the presence of a magnetic field. It works based on the Hall Effect principle, where the output changes when a magnet comes close to the sensor. This makes it ideal for position detection, speed measurement, and contactless switching applications.
It is widely used in Arduino, ESP32, robotics, and industrial automation projects.
