Re: Measure RPM with a Hall Sensor

The two components on the circuit board appear to be the pull down resistor and a capacitor. I now have it connected to the Pico and it is detecting when the magnet is present or not. I am using some micro-python I found on a Waveshare site. This is the code that is working for me : from machine imp...

Re: Measure RPM with a Hall Sensor

I have two sensors available to me. One is described as "A3144 Hall Effect Magnetic Field Sensor Arduino" Which is just a single small component with 3 wires coming out of it. The other is called a "3144 Hall Sensor Module - KY-003 - Switching - 3-pin" This has a similar sensor attached to a small P...

Measure RPM with a Hall Sensor

I have a Pico W and I hope to use it to measure RPM of a motor using a hall effect sensor. I have been searching on line and have found some examples of Python code on the Raspberry Pi to do this, but I can't seem to find anything specific for the Pico and MicroPython. Any suggestions as to how I co...
