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. ## Features - Hall Switch Integrated Circuit Using hall Effect Principle - Uses The Semiconductor Integrated Technology Manufacturing Magnetic Susceptibility of the Circuit - Its Input For the Magnetic Induction Intensity, the Output is a Digital Voltage Signal ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01NBE2XIR | | Best Sellers Rank | #25,103 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #2 in Hall Effect Sensors | | Brand Name | HiLetgo | | Connector Type | Screw | | Customer Reviews | 4.5 4.5 out of 5 stars (123) | | Manufacturer | HiLetgo | | Material Type | Copper | | Model | 3-01-1193 | | Mounting Type | DIN Rail Mount | | Number Of Contacts | 1 | | Number Of Poles | 1 | | Number of Positions | 1 | | Part Number | 3-01-1193 | | Voltage | 5 Volts | ## Product Details - **Brand:** HiLetgo - **Connector Type:** Screw - **Manufacturer:** HiLetgo - **Material:** Copper - **Mounting Type:** DIN Rail Mount - **Number Of Contacts:** 1 - **Number Of Poles:** 1 - **Voltage:** 5 Volts ## Images ![HiLetgo 5pcs Hall Effect Magnetic Sensor Module 3144E A3144 Hall Effect Sensor DC 5V for Arduino PIC AVR Smart Cars - Image 1](https://m.media-amazon.com/images/I/61gUkDoHh-L.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ ALL worked fine with a Raspberry PI 4B *by A***R on August 31, 2023* I needed a simple RPM tester so I put together some simple Python code.

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. ## Frequently Bought Together - HiLetgo 5pcs Hall Effect Magnetic Sensor Module 3144E A3144 Hall Effect Sensor DC 5V for Arduino PIC AVR Smart Cars - ALLECIN 20Pcs A3144 3144 Hall Effect Sensor OH3144 AH3144E 3Pins Magnetic Detector - EPLZON A3144 Hall Effect Sensor 3Pins Magnetic Detector for Arduino (Pack of 20 pcs) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/40465760-hiletgo-5pcs-hall-effect-magnetic-sensor-module-3144e-a3144-hall](https://www.desertcart.be/products/40465760-hiletgo-5pcs-hall-effect-magnetic-sensor-module-3144e-a3144-hall) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-03*
