Description

Gravity: Analog pH Sensor/Meter Kit V2

The DFRobot Gravity Expansion Shield and Sensors for Arduino - DFRobot SEN0161-V2, is specifically designed to measure the pH of a solution and reflect its acidity or alkalinity. The pH is a value that represents the acidity or alkalinity of a solution, also known as the hydrogen ion concentration index. The pH scale ranges from 0 to 14, with a pH of 7 indicating neutrality, a pH < 7 indicating acidity, and a pH > 7 indicating alkalinity.

As an upgraded version of pH meter V1, this product greatly improves precision and user experience. The onboard voltage regulator chip supports a wide voltage supply of 3.3 to 5.5V, making it compatible with both 5V and 3.3V main control boards. The free software library employs a two-point calibration method and can automatically identify two standard buffer solutions (4.0 and 7.0), simplifying beginner experiments.

With this product, a main control board (such as Arduino), and the software library, you can quickly build a pH meter that is plug and play, with no soldering required.
