Gravity: Analog pH Sensor/Meter Kit V2
Description Gravity: Analog pH Sensor/Meter Kit V2
The DFRobot Gravity: Analog pH Meter V2 is designed to measure the pH of a solution. The sensor can display the acidity or alkalinity. It is widely used in applications such as: Aquaponics, aquaculture, environmental testing. This is the V2 version, so it is improved compared to the V1. The user experience and precision have been greatly improved. The built-in voltage regulator chip supports the wide supply voltage of 3.3~5.5V. It is compatible with the main control board of 5V and 3.3V. The output signal is hardware filtered and has low jitter. The software library uses the two-point calibration method. It can automatically identify two standard buffer solutions (4.0 and 7.0).
With this product in combination with for example an Arduino and the software library you can quickly make a pH meter . You don't have to solder anything thanks to the Gravity interface of DFRobot.
The pH is a value that measures the acidity or alkalinity of a solution. It is also called the hydrogen ion concentration index. The pH is a scale of hydrogen ion activity in a solution. pH is used in applications such as medicine, chemistry, and agriculture. Usually, pH is a number between 0 and 14. Under standard thermodynamic conditions, the pH is 7. This means that the solution is neutral. At a pH lower than 7, it is acidic. At a pH higher than 7, it is alkaline.
Points of attention:
1. The BNC connector and signal conversion board should be kept dry and clean. Otherwise, it will affect the input impedance, resulting in inaccurate measurement. If it is damp, it should be dried.
2. The signal conversion card 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 the nylon pillar to fix the signal conversion card . Leave a certain distance between the signal conversion card and the surface.
3. The sensitive glass bubble in the head of the pH probe must avoid contact with the hard material . Any damage or scratch will cause the electrode to fail.
4. After completing the measurement, disconnect the pH probe from the signal conversion board. The pH probe should not be connected to the signal conversion board for a long time without power supply .
