More model informationFor a project to hold together the components needed for an ESP32 to read pH data from a probe that’s connected to a pH-4502c module. The system features a two-point calibration system that requires a keypad and little OLED screen for interaction.
Parts seen in the case are as follows: ESP-WROOM-32 microcontroller,pH-4502c sensor module, 4x4 membrane keypad, 128x64 ( or 128x32 ) OLED screen
Real-life implementation ( without back mount) :
