Solid performance
Using this to measure RPM on a custom RC car setup. It handles vibrations well and hasn't given any false readings. The only reason for 4 stars is the short cable length, but that's easily extendable.

Perfect for robotics projects
This sensor module works flawlessly with my Arduino-based smart car. The signal is clean and stable, making speed calculation very accurate. The included code disk fits standard motors perfectly.

Easy to integrate
The pinout is standard and easy to understand. Documentation could be slightly better, but if you know how photoelectric sensors work, this is plug-and-play. Very satisfied with the purchase.

Exactly as described
Arrived quickly and matched the description perfectly. The infrared beam is strong, and the detection of the code disk slots is crisp. Great component for any encoder project.

Reliable for student competitions
We bought ten of these for our university robotics team. They have held up well under heavy use during competition prep. The response time is fast enough for high-speed motor tracking.

Great value, minor alignment needed
Good quality for the price. I had to spend a little time aligning the emitter and receiver to get the best range, but once set up, it counts pulses reliably. Highly recommended for DIY enthusiasts.
Q: Can this sensor work with a 3.3V microcontroller like ESP32?
A: Yes, the module operates within a 3.3V to 5V DC range, making it fully compatible with ESP32, Arduino, and Raspberry Pi GPIO pins.
Q: What is the maximum RPM this sensor can accurately measure?
A: With a response time of under 10 microseconds, this sensor can accurately track speeds exceeding 20,000 RPM depending on the number of slots in your code disk.
Q: Is this sensor suitable for outdoor use in direct sunlight?
A: While the infrared filter helps, direct intense sunlight can interfere with optical sensors. We recommend shielding the sensor or using it in shaded areas for outdoor applications.
Q: How do I mount this to a non-standard motor shaft?
A: The module has standard mounting holes for screws. For non-standard shafts, you may need to 3D print a custom bracket to hold the sensor in place relative to your custom code disk.
Q: Does the package include the code disk shown in the images?
A: Yes, each order includes one transparent code disk specifically designed to fit the slot width of this sensor module.
