Description

The A3144 Hall Effect Sensor is a compact, reliable magnetic sensor module designed for detecting the presence or absence of a magnetic field. Each sensor in the pack uses the Hall effect principle to produce a digital output signal when exposed to a magnetic field, making it ideal for applications such as speed detection, proximity sensing, position measurement, and contactless switching. Operating on a wide voltage range (typically 4.5V to 24V), the A3144 features fast response time, high sensitivity, and low power consumption. Its three-pin design—VCC, GND, and Output—ensures easy integration with microcontrollers like Arduino, Raspberry Pi, and other electronic circuits. This pack of two sensors provides great value for prototyping and DIY electronics projects.
