PH measurement

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.

PH sensor connection

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.

Pin Description
- System ground.
+ Supply voltage from 3.3 V to 5.5 V.
A Analog signal output (0 V to 3 V).

1. The BNC connector and the signal conversion module must not get wet. Moisture may cause inaccurate measurements.
2. The signal conversion module must not be placed on a damp surface, otherwise it will affect the output impedance, causing inaccurate measurement.
3. The glass part of the electrode should not touch hard material. Any damage or scratches will damage the electrode.
4. After the measurement is completed, disconnect the probe from the module. The electrode should not be connected to the module for a long time without power.
