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: When I received the sensors they were all mangled because it was badly packaged Review: 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. ## 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 | | Batteries Included | No | | Batteries Required | No | | Brand | HiLetgo | | Colour | Black | | Connector Type | Screw | | Country of Origin | USA | | Customer Reviews | 4.5 4.5 out of 5 stars (115) | | Date First Available | 26 August 2019 | | Item Weight | 45 g | | Item model number | 3-01-1193 | | Manufacturer | HiLetgo | | Material | Copper | | Model | 3-01-1193 | | Mounting Type | DIN Rail Mount | | Number Of Contacts | 5 | | Number Of Poles | 5 | | Package Dimensions | 13.21 x 10.41 x 1.52 cm; 45 g | | Voltage | 5 Volts | ## Product Details - **Colour:** Black - **Connector Type:** Screw - **Material:** Copper - **Mounting Type:** DIN Rail Mount - **Number Of Contacts:** 5 ## 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/31Nwgc2EDRL.jpg) ![HiLetgo 5pcs Hall Effect Magnetic Sensor Module 3144E A3144 Hall Effect Sensor DC 5V for Arduino PIC AVR Smart Cars - Image 2](https://m.media-amazon.com/images/I/41jZFu87lJL.jpg) ![HiLetgo 5pcs Hall Effect Magnetic Sensor Module 3144E A3144 Hall Effect Sensor DC 5V for Arduino PIC AVR Smart Cars - Image 3](https://m.media-amazon.com/images/I/51+Du5sRIiL.jpg) ![HiLetgo 5pcs Hall Effect Magnetic Sensor Module 3144E A3144 Hall Effect Sensor DC 5V for Arduino PIC AVR Smart Cars - Image 4](https://m.media-amazon.com/images/I/515+-E3Ex9L.jpg) ![HiLetgo 5pcs Hall Effect Magnetic Sensor Module 3144E A3144 Hall Effect Sensor DC 5V for Arduino PIC AVR Smart Cars - Image 5](https://m.media-amazon.com/images/I/517uGRarn7L.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 ### ⭐⭐ Review *by C***S on 19 February 2021* When I received the sensors they were all mangled because it was badly packaged ### ⭐⭐⭐⭐⭐ Review *by A***R on 31 August 2023* I needed a simple RPM tester so I put together some simple Python code.
