## Customer Reviews

### ⭐⭐⭐⭐⭐ Funcional
*by C***S on November 10, 2024*

Dispositivo funcional, cumple con las expectativas

### ⭐⭐⭐⭐⭐ Great for the Price
*by K***Y on April 17, 2024*

Sensor worked great. Cheap and effective, with a built-in resistor. A built-in LED turns on when the sensor is in close proximity to a magnet.Wiring for arduino should be done as follows (see picture):-Negative (left): ground-Center: 5v-Right (S): input pin.The sensor should be coded as '1' when no magnet is present and '0' when the magnet is in close proximity.

### ⭐⭐⭐⭐⭐ Quick shipping, all units work as intended.
*by J***A on November 1, 2023*

I already had code written for these to operate with my Uno R3 and Mega2560 setups. These were a great replacement for 3 separate projects. I placed a rare earth magnet on a harmonic balancer of an engine, one on a VAWT blade and one glued to a CDrom just to observe high speeds. These worked for all I need, plus many things I wouldn't. So I would recommend these for several uses.
