Speed Measurement Hall Sensor Module 3144E Hall Switch Motor Tachometer Module
Feature: 1. Working voltage: 3.3 -5V 2. Use the 3144E Switching Hall Sensor. 3. When the sensor senses a magnetic field, the digital output is low and the signal light is on; if no magnetic field is sensed, the digital output is high and the signal light is off. 4. With power indicator and signal indicator. 5. Output mode: digital switch output (0 and 1) AO port is invalid 6. LM393 comparator output, clear model, good waveform, strong drive capability, more than 15mA. 7. Provide fixing bolt holes for easy installation and fixing. 8. It can be used for motor speed, position detection, etc.
Module Interface Description: VCC: positive power supply 3.3-5V GND: negative one DO: digital output module, the output of low magnetic induction AO: Hall output voltage in real time
Sensor function introduction: The 3144 Hall switch IC is based on the Hall effect principle and uses a magnetic sensing circuit that manufactures semiconductor integrated technology. It consists of a voltage regulator, a Hall voltage generator, a differential amplifier, a Schmitt trigger, a temperature compensation circuit and a set. The open-circuit output stage consists of a magnetic sensing circuit. The input is magnetic induction and the output is a digital voltage signal. The sensor has the characteristics of small volume, high sensitivity, fast response, good temperature performance, high precision and high reliability.
