Calibrating an Analog pH Sensor (with Linear Algebra)
DFRobot Analog pH Sensor is compatible with both Arduino and Raspberry Pi. Our friend DavyBot gives you a general overview of linear functions and interpolation in this video. Plus he will show you how to write custom code to use this sensor on an unsupported platform (Espruino).
