Gravity Analog pH Sensor Meter Kit V2

Description of Gravity Analog pH Sensor Meter Kit V2 DFRobot Gravity: Analog pH meter V2 is specifically designed to measure the pH of the solution and reflect the acidity or alkalinity. It is commonly used in various applications such as aquaponics, aquaculture, and environmental water testing. As an upgraded version of pH meter V1, this product greatly improves the precision and user experience. The onboard voltage regulator chip supports the wide voltage supply of 3.3~5.5V, which is compatible with the 5V and 3.3V main control board. The output signal filtered by hardware has low jitter. The software library adopts the two-point calibration method, and can automatically identify two standard buffer solutions (4.0 and 7.0), so simple and convenient. You may also check Liquid Sensor Selection Guide to get better familiar with our liquid sensor series. With this product, the main control board (such as Arduino) and the software library, you can quickly build the pH meter, plug and play, no welding. DFRobot provides a variety of water quality sensor products, uniform in size and interface, not only meeting the needs of various water quality testing, but also are suitable for DIY of multi-parameter water quality testers. 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.
