LM393 3144 Hall Effect Magnetic Field Sensor Module

LM393 3144 Hall Effect Magnetic Field Sensor Module

1 Size: 2.7 cm*1.4mm
2 Main chip: LM393, 3144 Hall sensor
3 Working voltage: DC 5V

Two module interface description (4-wire system)
1 VCC external 5V voltage
2 GND External GND
3 DO small board digital output interface (0 and 1)

Three module features:
1. With power indicator and signal output indication.
2. Single channel signal output.
3. The module has no trigger and outputs a low level; the module has a trigger and outputs a high level.
4. Adjustable sensitivity (fine adjustment).
5. When there is magnetic field cutting, there will be signal output.
6. The output switch value of the circuit board can be directly connected to the single-chip microcomputer or our relay module, buzzer module, etc.
7. It can be used for motor speed measurement/position detection and other occasions.
