The Photo Encoder Motor Speed Sensor Kit is an optical (photoelectric) sensor module used to detect rotation and measure the speed of a motor or rotating shaft. As the slotted disc spins through the sensor's optical gap, it generates pulses that your controller counts to calculate RPM. It's a popular choice for hobbyists, students, and engineers building motor control, robotics, automation, and measurement projects.
Key features
- Photoelectric encoder design for contactless speed and rotation sensing
- Outputs clean digital pulses that are easy to read with common microcontrollers
- Compact module that fits neatly into DIY and prototyping builds
- Simple wiring suitable for beginners and experienced makers alike
Typical uses
- Measuring motor RPM in robotics and automation projects
- Speed feedback for DC motors, fans, and rotating mechanisms
- Counting rotations, pulses, or revolutions in measurement setups
- Educational kits, Arduino and microcontroller experiments
How to choose / tips
- Confirm the operating voltage matches your controller board before wiring.
- Keep the slotted disc clean and aligned within the optical gap for stable readings.
- Pair it with a microcontroller to convert pulses into accurate speed values.
