3144E Hall Effect Sensor Module

Product Description

The AH3144 Hall sensor is a single-ended digital output Hall IC excited by a single magnetic pole. The sensor chip has built-in circuit units such as a reverse voltage protector, voltage regulator, temperature compensation circuit, Hall voltage generator, signal amplifier, Schmit trigger, and open-collector output driver.

Features

• Designed with a high-quality double-sided PCB with power indication and signal indicator
• Work voltage:3.3V-5.0V
• High sensitivity and fast response
• Good temperature performance, it has high accuracy and high reliability.
• Output form: digital switch, analog A0 port is invalid
• When the sensor senses the magnetic field, the output is low and the signal light is on; Conversely, the output level is high and the signal light is off
• With LM393 comparator, it directly outputs high and low levels, has strong driving capability, and the output current reaches 15mA
• There are mounting holes for easy installation
• Wiring instructions:
  1. VCC -power positive
  2. GND -power supply negative
  3. DO -TTL digital output
  4. AO -analog output (different distance output, different voltage)

Typical applications

• motor speed measurement
• detect motor position/detection
