HALJIA Hall Sensor Motor Speed Module 3144E Single Open Circuit Magnetic Field Measurement Compatible with Arduino

1. Working voltage: 3.3--5V 2. Use the 3144E hall switch sensor.3. When the sensor is sensitive to the magnetic field, the digital output is low, the signal light; if not sensitive to the magnetic field, the digital output high, the lights are not bright.4. With power indicator and signal indicator.5. Output form: Digital switching output (0 and 1), Hall real-time analog output.6. Using LM393 comparator output, type clean, good waveform, driving ability, more than 15mA.7. A fixed bolt holes for easy mounting.8. Can be used for motor speed, position detection.Packing List:1 * Hall Sensor Module
