PH Limit: This potentiometer is to sets a limit value of the pH sensor circuit that causes the red LED to light up and the Do pin signal to turn ON. Connect Po to Analog input A0 on Arduino, and G to ...

This Arduino project reads pH values from a pH sensor and sends the data to the ThingSpeak IoT platform via Wi-Fi. The project utilizes an analog pH sensor connected to analog pin A0 and communicates ...

In this article, we present a pH meter that can accurately measure the pH value of a solution. We use a dedicated sensor, the Arduino UNO R4 Minima board.
