This is a pH sensor designed for use with the SmartGarden3 system.
Here is the assembly manual for adding this to the SmartGarden3 Hydroponics System.
Hydroponics Turbidity and pH Sensor Assembly Manual
This second generation pH meter pro greatly improves the precision of the sensor. The output signal filtered by hardware has low jitter. It uses an industry electrode and has a built-in simple, convenient, practical connection and long life, very suitable for online monitoring.
This industry pH combination electrode is made of a sensitive glass membrane with low impedance. It can be used in a variety of PH measurements with fast response, good thermal stability. It has good reproducibility, difficult to hydrolysis, and basically eliminates the alkali error. Between 0 to 14 pH range, the output voltage of the electrode is linear. The reference system which consists of the Ag/AgCl gel electrolyte salt bridge has a stable half-cell potential and excellent anti-pollution performance. The ring PTFE membrane is suitable for long-term online detection.
The pH is a value that measures the acidity or alkalinity of the solution. It is also called the hydrogen ion concentration index. The pH is a scale of hydrogen ion activity in solution. The pH has a wide range of uses in medicine, chemistry, and agriculture. Usually, the pH is a number between 0 to 14. Under the thermodynamic standard conditions, pH=7, which means the solution is neutral; pH<7, which means the solution is acidic; pH>7, which means the solution is alkaline.
