## Description

Gikfun A3144/OH3144/AH3144E Hall Effect Sensor Magnetic Detector for Arduino (Pack of 20pcs) EK1325: desertcart.com: Industrial & Scientific

Review: Great for an rpm calculator - This sensor is more sensitive than the sparkfun hall effect sensor and worked great for my purposes. It's basically a drop-in replacement for the sparkfun one but with much better switching characteristics. To use this sensor, you need to add a pull-up resistor on the OUTPUT pin. It will sink the voltage to 0 when a magnet is nearby. Look up the datasheet for A31444 to find the pinout. Overall, I'm really happy with this little device.
Review: Fixed my issue - Was great for fixing my t16000m z axis

## Questions & Answers

**Q: Are these latching Hall effect sensors?**
A: They are not latching

**Q: pinout diagram?**
A: Search for A3144 circuit. By itself it is not usable.

**Q: Do these work on qs 205 motor**
A: No you will need to work on the motor yourself. These have not been trained to do that type of work.

**Q: Will it wok with 3.3 volts?**
A: There is an in-law problem and as such these are not to work together.

### ⭐⭐⭐⭐⭐ Check You tube for good info
*by Z***Z on July 20, 2021*

The product comes with no application note or any significant data, but You Tube is your friend for this product. I have already prototyped the circuit I want based on the data in the you tube videos, now I have to implement it in real life and put it through it's paces. The prototype worked as expected.
