Tutorial for analog pH sensor that's compatible with both Arduino and Raspberry Pi
Youtube Channel: Davy Wybiral
This video is an overview and tutorial for an analog pH sensor that's compatible with both Arduino and Raspberry Pi but I'll also give a general overview of linear functions and interpolation. Plus I'll show you how to write a custom code to use this sensor on an unsupported platform (Espruino).
Measuring pH is pHun! (...I'm here all night folks.)
