Gravity: Analog pH Sensor - Measurement Kit V2
DFRobot Gravity: Analog pH meter V2,It is specially designed to measure the pH of the solution and reflect the acidity or basicity. It is widely used in a variety of applications such as aquaponics, aquaculture and environmental water testing.
Being an upgraded version of pH meter V1, this product greatly improves the precision and user experience. Built-in voltage regulator chip supports wide voltage supply of 3.3 ~ 5.5V, compatible with 5V and 3.3V main control board. The output signal filtered by the 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), that simple and convenient.
With this product, main control board (such as Arduino) and software library, you can quickly build the pH meter, plug and play method, without welding. DFRbot provides a variety of water quality sensor products, uniform size and interface, which not only meet the needs of various water quality tests, but are also suitable for the DIY of the multi-parameter water quality tester.
PH is a value that measures the acidity or alkalinity of the solution. It is also called the hydrogen ion concentration index. PH is a scale of hydrogen ion activity in solution. PH has a wide range of uses in medicine, chemistry and agriculture. Usually, the pH is a number between 0 and 14. Under thermodynamic standard conditions, pH = 7, this means the solution is neutral; pH<7 bu, çözeltinin asidik olduğu anlamına gelir; pH>7, that means the solution is alkaline.
Attention: 1. The BNC connector and signal conversion board must be kept dry and clean, otherwise it will affect the input impedance, resulting in an inaccurate measurement. If it is moist, it must be dried.
2. The signal conversion board cannot be placed directly on a wet or semiconductor surface, otherwise it will affect the input impedance, resulting in inaccurate measurement. It is recommended to use nylon column to fix the signal conversion board, allow a certain distance between the signal conversion board and the surface.
3. The delicate glass bubble in the head of the pH probe should avoid contact with hard material. Any damage or scratches will cause the electrode to fail.
4. After completing the measurement, remove the pH probe from the signal conversion card. PH probe should not be connected to signal conversion board without power supply for a long time.
