Here's a simple Arduino code to read the pH value from the sensor and print it to the Serial Monitor. If using an LCD, you can add the necessary code to display the value on the LCD. alibrating the ...

Connect the pH probe to the amplifier (interface) module, then connect the module’s output to an Arduino analog input. In your Arduino code, read the analog voltage, convert it to pH (using ...

Generally, the pH modules available commercially are very expensive. We focus on discussing the design of an affordable pH module, interfacing it with Arduino, NodeMCU and Raspberry Pi boards.

Researchers utilized Arduino microcontroller on its features to perform hardware and software integration. Powered by integrated development environment multiple sensors were utilized in the project ...
