Convert variable reluctance (VR) sensor signals into a clean, reliable digital square wave with this compact and easy-to-use signal conditioning module. Designed for versatility, this board allows you to interface VR sensors—commonly found in wheel speed sensors, crankshaft position sensors, transmission speed sensors, and more—with systems that require a Hall effect-style input. Whether you're working on a custom automotive build, standalone ECU setup, or retrofitting modern electronics into older platforms, this module ensures accurate signal conversion across a wide range of applications. Key Features Universal Compatibility Works with most variable reluctance sensors and is compatible with a wide range of engine management systems, ECUs, data loggers, and digital controllers that require a square wave input. Clean Signal Conversion Converts noisy, low-amplitude VR signals into a stable 0–5V square wave output with matching frequency for accurate readings. Wide Application Range Ideal for: Wheel speed sensors (ABS tone rings) Crankshaft and camshaft position sensors Transmission speed sensors Custom fabrication and motorsport applications Improved Low-Speed Detection Maintains reliable signal output even at low RPMs where raw VR signals are typically weak or inconsistent. Compact & Easy Integration Small footprint allows for easy installation in tight spaces. Simple wiring makes it suitable for both DIY builders and professional installers. Robust Design Built for automotive environments with stable performance under vibration, electrical noise, and temperature variation. Why Use a VR Conditioner? Variable reluctance sensors produce an analog sine wave signal that varies with speed and can be difficult for many modern systems to interpret directly. This module converts that signal into a digital square wave, making it readable by ECUs and controllers that expect a Hall effect-style input. Typical Use Cases Converting legacy sensor signals for modern standalone ECUs Integrating aftermarket digital dashboards Custom CNC, speed measurement, or automation projects Swapping drivetrains or transmissions with mismatched sensor types Input: Variable Reluctance (VR) sensor Output: Digital square wave (0–5V) Power Supply: 7v-16v Dimensions: 22mm*35mm
