Ph Senor Arduino Interfacing Tutorial | Working, Calibration Method & Code

In chemistry, pH is a scale used to specify how acidic or basic a water-based solution is. Acidic solutions have a lower pH, while basic solutions have a higher pH. Thus Ph sensor has the ability to determine the Ph of any solution, i.e it tells whether the substance is acidic, basic or neutral in nature. By knowing the Ph, we can monitor the water quality in Agricultural Farm and also in Fish Farming. Similarly, Ph Sensor has a wide range of applications like wastewater treatment, pharmaceuticals, chemicals & petrochemicals. In this basic tutorial, we will learn how to interface Gravity Ph Sensor with Arduino. We will design a simple Ph Meter and display the Ph value on OLED/LCD Display. We will also learn about the construction & working of the Ph Sensor. Finally, we will learn the calibration method which will determine the correctness and accuracy of the sensor. The Ph Sensor can also be interfaced with other higher-level microcontrollers like NodeMCU ESP8266 & STM32 which I will discuss in the future.
