Hall Sensor Motor Speed Module 3144E Single Open Circuit -Blue
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.
