A27 PH Value Detection Sensor Module [5V] [0-14pH]

Description:
PH metering is a sufficient way for measuring the hydrogen ion concentration of water-based liquid and it is a useful instrument for the detection acidity of water.
The PH sensor module can be used to interface PH sensors with BNC connectors to a microcontroller board such as the popular Arduino Uno. The module featured an offset potentiometer, so you can change the analog readout and make it work with an Arduino board.
A pH meter provides value as to how acidic or alkaline a liquid is. The basic principle of the pH meter is to measure the concentration of hydrogen ions. Acids dissolve in water forming positively charged hydrogen ions (H+). The greater this concentration of hydrogen ions, the stronger the acid is.
