Dec 29, 2009 · I learned something today. I learned that a variable reluctance sensor cannot be simulated with a square wave using an Arduino digital output. This will sound obvious to …

Apr 1, 2013 · Are you certain that's the speed sensor and not the rev counter? A small AC voltage whose amplitude and frequency increase with the speed of rotation of the sensor is exactly …

Dec 31, 2017 · Hi, I was planning to read the rpm of my motorcycle with the arduino, I thought that the crank shaft sensor was a hall effect sensor and that I could use the square wave that was …

Jun 19, 2018 · Hi guys, Read some topics about variable reluctance / inductive / magnectic pickup sensors on this forum, but didn't find any clear solution. I have a magnectic pickup sensor (see …

Jun 22, 2021 · In the original engine, this tachometer was using input from a variable reluctance sensor (inductive pickup?). This sensor was isolated from the rest of the electrical system and …

Apr 22, 2014 · Hi everyone, I have an old Alfa Romeo with a speedometer that uses a cable drive from the gearbox. For various reasons, I want to convert this from mechanical to and …

Apr 6, 2025 · @ledsyn, VR sensor = variable reluctance sensor/transducer, its a robust two wire sensor that puts out a varying AC voltage . Your favorite search engine can define it way …
