How to use the A3144 Hall Effect Sensor with your PICO

Hall effect sensor - Magnetic Switches are very useful in many projects. Anywhere you want a switch that can't be touched, is a good place for a hall effect sensor. In this video, Chris reviews the data sheet, wiring and coding for the A3144 sensor.

Shortest , most educational video for the a3144 I have seen. Thank you

Nicely done Chris. Looking forward to seeing the project when it's ready.

Thank you, very much appreciated. I will be announcing more information about the "big project" within a few weeks. I am getting excited about it and I think it will be well received in our community.
Cheers!

Thank you! Your Pi Pico series of tutorial videos are helping me expand my expertise from the Arduino. I have a lot of 5v sensors on hand. Maybe in a future video you could address considerations of using 5v sensors with a 3.3 Pi Pico?

Glad to help!
I have been thinking about that, but not sure when I can get around to it. I am about to launch a new series utilizing PICOS that will take up a serious amount of time. I am very hopeful everyone will enjoy that series.
Cheers!

With the input voltage into the A3144 at 5V. What is the voltage from the output pin 3. Do you have worry about damaging the Pi Pico inputs 3.3 volts?

HI RBHaveman,
The output from this device is an open collector...
Open-Collector 25 mA Output … Compatible with Digital Logic
When the sensor is active, it is connected to zero volts (Ground). When the sensor is inactive, it is pulled high by the PICO, thus 3.3V.
Cheers!
