The sensor I chose was an Allegro hall effect sensor A1120EUA-T. It cost approximately £1 from CPC. For any old-timers out there, no it isn’t one of these. Here is the pin assignment : See more I wanted a cheap, compact magnet that I would be able to easily mount on the printer so I ordered some from Amazon. There was no real … See more In the photo above the red wire is Vcc (3.3V), the brown wire is ground and the orange wire is Vout. Here is the circuit diagram : Vcc is connected to the 3.3V supply on the Pi’s header (pin 1). GND is connected to pin 6. … See more I quickly found out that the triggering distance was approx 15mm. This made the setup perfect for my application. This assumed that the end of the cylinder is inline with the flat … See more The Python script I wrote simply configured the GPIO pin as an input, pulled it high and setup a call-back function.
