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 ...

Connect the pH sensor module to the Arduino: VCC to 5V; GND to GND; AO (Analog Output) to A0 (Analog Pin 0) If using an LCD display, connect it according to its datasheet or use an I2C LCD for easier ...

The pH meter project features open software and open hardware design circuit which can be connected with an electrode pH sensor made of glass. The device is termed as pHduino which can operate by ...

An ASK based RF receiver module with 433MHz carrier frequency is used to demodulate and receive data transmitted by sensor node’s RF transmitter module. Microcontroller. Arduino Nano board is used as ...

This paper presents an Arduino-based monitoring system that measures four physicochemical parameters of water: pH, temperature, turbidity, and electrical conductivity to identify possible water ...
