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 ...

Interfacing IR Sensor Module with Arduino. Build Time: 2-4 hours. | Cost: $5-10. | Difficulty: suitable for beginners. What You'll Learn: You will learn to handle digital input/output, interface an IR ...

As mentioned earlier, this circuit takes its power directly from the Arduino UNO R4 board’s 5 V and GND pins. The pH-detection module’s pin P0 was connected to the Arduino board’s analog pin A0. This ...

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 ...

This paper presents a novel differential current mode read-out circuit for the Ion Sensitive Field Effect Transistor (ISFET), as a pH sensor. It uses six Operational Floating Current Conveyors (OFCC), ...
