Description
The PH pro V2 analog sensor allows you to measure thePH ofa solution, acidity or alkalinity. It is equipped with anindustrial electrodewith long life and simple connection to the module. The electrode is made of a glass PTFE membrane with low impedance. The sensor allows to measure PH in the rangefrom 0 to 14. It is powered by a voltagefrom 3.3 V to 5.5 V. Arduino compatible module, for simple connection you can use Gravity -DFRobot Expansion Shield.
PH is a value that determines the acidity or alkalinity of a solution. PH value is a scale of hydrogen ions activity in the solution. PH value is most commonly used in medicine, chemistry and agriculture. Usually PH is measured in valuesfrom 0 to 14. When the PH value is 7 - the solution is neutral, PH < 7 the solution is acidic, and when PH > 7 the solution is basic.
The sensor is equipped with aGravityconnector, which allows simple connection of the sensor with the main module. It communicates throughan analoginterface. It is powered from3.3 V to 5.5 V. It works with microcontrollers equipped with digital to analog converter. The electrode is connected with the module viaBNCconnector.
