## Overview

The HiLetgo 5pcs Hall Effect Magnetic Sensor Module 3144E operates at 5V DC, using semiconductor integrated technology to convert magnetic induction into a digital voltage signal. Designed for easy integration with Arduino, Raspberry Pi, PIC, and AVR systems, these compact sensors provide reliable, non-contact magnetic detection ideal for RPM measurement, position sensing, and smart car applications. Each pack includes five durable modules, making it a cost-effective choice for prototyping and industrial projects.

## Description

Description: 1. Non-Contact Switch 2. Hall Switch Integrated Circuit Using hall Effect Principle, 3. USES The Semiconductor Integrated Technology Manufacturing Magnetic Susceptibility of the Circuit, 4. It is by the Voltage Regulator, Hall Voltage Generator, Differential Amplifier, Schmidt Triggers, Temperature Compensation and the Open Collector Output Stage Circuit Composed of Magnetic Sensitive Sensor Circuit 5. Its Input For the Magnetic Induction Intensity, the Output is a Digital Voltage Signal Package Included: 5* HiLetgo Hall Effect Magnetic Sensor Module

Review: ALL worked fine with a Raspberry PI 4B - I needed a simple RPM tester so I put together some simple Python code. Connected the Hall effect board to my PI. The board has '-' clearly marked for GND at the connector. I connected that to pin 6 on my PI. '+' is not marked on the board but is the middle pin, so I connected that to pin 2, 5V, on my PI. Then the status line, marked with an 'S' to GPIO18 which is physical pin 12 on the PI. Note the boards status line is open collector, meaning it is either open or GND. It does NOT swing up 5V. In the Python code I did set the GPIO18 pin to be pulled up by the PI, not sure if I needed that since that may be the default. I tested my simple code on all 5 of the boards I received and they all worked as expected. I could easily detect an RPM from 30 to 400 RPM. Sorry that is NOT the limit of the circuit, just my hand tool. This little board is very inexpensive and works perfectly.
Review: Works well - note to test your magnet polarity. - This worked well for me. Note however that the sensor is sensitive to the polarity of the magnet. Make sure to test it and orient the magnet and which side of the sensor works with it.

## Questions & Answers

**Q: Is center pin +5V?  Why not show power hookup? It is different than most.**
A: Signal pin is marked "S". Ground pin is marked "-". Unmarked center pin is "+5V".

**Q: Does this work on 3.3v arduino?**
A: Yes. It works on both 3.3v and 5v.

**Q: do these have an LED?**
A: Yes, LED turn on when the magent is present.  Output goes low.

This worked well for me. Note however that the sensor is sensitive to the polarity of the magnet. Make sure to test it and orient the magnet and which side of the sensor works with it.

### ⭐⭐⭐⭐⭐ Good learning tool
*by R***T on March 26, 2023*

Wired this circuit board with a built in LED, to a 3 to 5 Volt power supply and monitored the output signal with both a digital multimeter and Oscilloscope. Moving a magnet at different speeds across the Hall Effect Transistor, enables me to view a varying square wave shaped pulse width modulated signal. My main focus was to use this as a learning tool, and I was not disappointed. The price is right as well.
