Exceeded expectations

I was worried about noise interference, but this module handles it well. The pulse counting is precise, making it ideal for flow meter applications. Fast shipping and well-packaged too.

Easy to integrate with Arduino

Plug and play with my Arduino Uno. The documentation online was helpful, and the module responded immediately to my test code. I'm using it for limit switching on a CNC axis, and it hasn't failed once.

Good value, works as expected

Solid sensor for the price. It detects magnetic pulses reliably for my wheel encoder setup. The only minor issue is that the included pins were a bit loose, but I replaced them easily. Overall, a great purchase.

Reliable industrial prototype component

We tested several sensors for a prototype conveyor belt counter, and this one offered the best consistency. The digital signal counting is accurate, and the build quality feels durable enough for light industrial use.

Perfect for RPM monitoring

I used this module to build a tachometer for a small DC motor project. The signal output is clean and stable, even at high speeds. The adjustable potentiometer makes it easy to fine-tune the sensitivity. Highly recommended for hobbyists.

Great for university projects

Bought five of these for our final year engineering project involving motor speed control. They all worked perfectly out of the box. The LED indicator is very useful for debugging connections.

5 FAQ

Q: What is the maximum current this module can handle?

A: The output pin is designed for logic-level signaling and should not source or sink more than 20mA. It is intended to connect to microcontroller GPIO pins, not to drive heavy loads directly.

Q: Does this come with connecting wires?

A: The standard package includes the PCB module and a set of header pins for soldering. Connecting wires are usually sold separately, but many users utilize standard jumper cables.

Q: Is the detection distance fixed or adjustable?

A: The detection distance is adjustable via the blue potentiometer on the PCB. You can tune it from approximately 2mm up to 20mm depending on the strength of the magnet used.

Q: Can this sensor detect non-magnetic materials?

A: No, this module relies on Hall effect or magnetic induction principles, so it requires a magnetic field or a magnet attached to the rotating object to generate a pulse.

Q: Can I use this outdoors in the rain?

A: This module is not waterproof or weather-sealed. If you plan to use it outdoors, you must house it in a protective enclosure to prevent moisture damage.
