Easy to integrate
Very simple wiring. Connected VCC to 5V, GND to ground, and output to an interrupt pin. Detected my neodymium magnet immediately.

Perfect for RPM projects
Used this to measure fan speed on my 3D printer. The response is instant and the signal is clean without needing extra debouncing code.

Solid performance
Great for school projects. The detection distance is short, so make sure your magnet placement is precise, but otherwise very stable.

Compact and effective
Small footprint makes it easy to mount in tight spaces. The LED indicator is helpful for debugging during setup.

Reliable counting
I built a conveyor belt counter using three of these modules. They have been running 24/7 for two weeks without a single missed count.

Good value sensor
Works exactly as described. Just remember you need a magnet close to the sensor face for it to trigger. Great for counting wheel rotations.
Q: What type of magnet is required for activation?
A: Any standard permanent magnet will work. For best results at the maximum detection range, we recommend using a neodymium magnet.
Q: Is the output analog or digital?
A: The output is digital (TTL). It switches LOW when a magnetic field is detected and remains HIGH when no field is present.
Q: Does this module work with 3.3V microcontrollers like ESP32?
A: Yes, the module operates within a 3.3V to 5V range, making it fully compatible with ESP32, ESP8266, and standard 5V Arduino boards.
Q: Can this detect the speed of a spinning motor shaft?
A: Absolutely. By attaching a small magnet to the rotating shaft, this sensor can accurately count revolutions to calculate RPM.
Q: How do I mount this sensor?
A: The PCB includes two standard mounting holes that accept M3 screws, allowing for secure installation on your project frame.
