DFRobot Gravity: Analog pH meter V2 is specifically designed to measure the pH of the solution and reflect the acidity or alkalinity. DFRobot pH sensor 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 precision and user experience. The onboard voltage regulator chip supports a wide voltage supply of 3.3~5.5V, making it compatible with 5V and 3.3V main control boards. 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), making it simple and convenient to use.
With this product, the main control board (such as Arduino) and the software library, you can quickly build the pH meter with plug and play functionality, no welding required.
