Using a pressure sensor for bed leveling using nozzle as probe
-
I am looking to use a pressure sensor within my hot end assembly so I can level the bed and calculate nozzle offset without the need of a separate probe. I have seen a few different DIY videos on the internet however they all seem to leave out some important details. This pressure sensor seems like it could be a good fit due to its size and shape. However I am unsure as to how I would wire it since I think I need a separate board to turn its analog signal into a digital one. I am looking to connect this to my duet 3 mini 5+. Would this be a good pressure sensor to use and how would I actually wire it to my board?
There is also this one which seems to come with the board it needs. However this one is much larger and also has output wires labeled OT and SCK which don't seem to correlate with the labels of the duet mini IO pin names.
Thank you for you help and if I overlooked a much easier way to do this please let me know.

@SamKudarauskas the second one uses the HX711 chip, which is too slow to be used for bed probing. The first one is a Force Sensitive Resistor (FSR) and we mention those in our documentation about connecting Z probes. See https://docs.duet3d.com/User_manual/Connecting_hardware/Z_probe_connecting#force-sensitive-resistors.
