Hall Sensor Velocity Measurement and Counting Sensor A3144E

Hall sensor module is used for magnetic field detection, which adopts 3144E Hall Switch Sensor.

Module Interface Description

• VCC: connect to positive 3.3-5V
• GND: connect to negative
• DO: Digital signal output on module, outputs low level when magnetism available
• AO: Hall real-time voltage output

There are two outputs on the module

• AO, Hall real-time output
• DO, the Hall signal output after being regulated by the comparator

Module features

• Small size: 32mm X 14mm
• With a 3mm mounting screw hole
• You can use 3-5.5v DC power supply
• With Hall real-time output signal
• More stable output signal after being regulated by comparator
• Comparator output capability: 16mA
• With power indicator
• With indicator for comparator output
