Dual Variable – Reluctance Sensor Interface Module – Stepper Motor Based Incremental Rotary Encoder

https://www.electronics-lab.com/project/dual-variable-reluctance-sensor-interface-module-stepper-motor-based-incremental-rotary-encoder/

This project offers a dual−channel low component count interface solution for ground-referenced variable reluctance sensors. Each of the two identical channels interfaces with a variable−reluctance sensor, and continuously compares the sensor output signal to a user−programmable internal reference. An alternating input signal of appropriate amplitude at IN1 or IN2 will result in a rectangular waveform […]
