Review: El circuito con display no me ha convencido mucho, pero yo compre el kit por el sensor Hall que trae, y estoy contento con él. Es como el de la imagen, con cuerpo metálico, y con tuercas y arandelas, y también trae un pequeño imán. El sensor funciona correctamente.. El circuito no me convence del todo, porque la cuenta puede oscilar, ya que parece que calcula las RPM a partir de medir el tiempo entre pulsos, sin hacer medias, y una pequeña diferencia de tiempo en alguna de las revoluciones hace que los números cambien. Otra característica del contador es que, si el sensor deja de detectar pulsos, no se indica inmediatamente 0rpm, sino que se mantiene la última cuenta unos segundos. A pesar de estas cosas, el conjunto está bien para su precio, que es lo que puede costar solo un sensor similar de una marca barata más común.

## Questions & Answers

**Q: Can you recommend a 110v power supply for the tach here from Amazon?**
A: I save old wall warts, those plug-in AC adapters that you plug in the wall, and then into your device, and I found one of them that supplied the recommended voltage, cut off the device plug and connected it to the tachometer power wires.

**Q: Will this work on lawnmowers?**
A: If you can install the magnet and sensor in lawnmower. i think it can work with it. thank you@

**Q: Is there a way to output the tach signal to a data acquisition system that reads in voltage?**
A: This hall sensor acts as a NO switch. Meaning that voltage/current are allowed to pass only when the magnet is near the sensor. For use as a tachometer, you would be reading pulses/second, or frequency. So data logging voltage wouldn't really work unless you worked some excel magic afterwards.

**Q: what is the maximum length of the sensor wire? 44 inches is too short for my need.  Can I lengthen it?**
A: I installed this on my combine to measure the fan RPM speed. I needed to add more wire to reach the display mounted inside the cab. The total length of the wire is over 15 feet. I believe it would work at even a greater length.
The unit works great.

*by J***P on 20 December 2022*

The device is easy to install and it came with instructions. You will need a suitable 12v power supply (I used an old network router's power supply) to provide 12v power to the device. I mounted the display in an aluminium enclosure to make it look neater and to protect the electronics. The device works well, however, it is a little slow to update its display especially when stopping the machine. Well worth fitting to a milling machine/lathe/pillar drill or similar.
