The A3144 Hall Effect Sensor switches its digital output between high and low when a magnetic field crosses its sensing face. No physical contact happens. The hall effect switch runs on 3V to 6.5V and draws only 4mA at 5V, connecting directly to any Arduino or ESP GPIO pin.
The a3144 hall effect sensor switch has an open-collector NPN output requiring a pull-up resistor on the signal line. Skipping the pull-up gives floating or incorrect readings. Operating temperature spans minus 40°C to plus 85°C.
Robotics makers, and hobbyists use the hall effect sensor for RPM counting and position detection. StemVolt provides sensor with trusted quality, ensuring reliable performance and easy usability.
