* according to the signal sending by your own pH probe if you don't use the DFRobot pH sensor kit probe * same circuit with different probe return different voltage value for buffer4.0 or buffer 7.0 ...

This project utilizes the DFRobot SEN0249 pH Sensor with an ESP32 microcontroller to measure pH levels. The code is written in C++ using the PlatformIO framework within the Arduino environment.

The pH of a solution can be determined using a pH meter or a pH indicator solution. The module utilises Hydrogen-ion activity also known as the “proton activity” for measuring pH of the liquid. This ...

In this project we are going to make an Arduino pH Meter and learn how to measure the pH of a liquid solution using a gravity pH sensor and Arduino. A 16x2 LCD is used to show the pH value on the ...
