You literally pressed 2 buttons, the CAL button and the CFM (confirm) button. This goes hand in hand with a temperature sensor of course. (after rinsing) It does the same thing, it waits for the pH to stabilise at 4 and then you press confirm. It then asks you to put the probe into your pH 4 solution. You select calibration, it displays a request for pH 7, you put the probe into your pH7 buffer solution, it stabilises at pH 7, once it is happy, you can press confirm and it stores the offset. It needs to be like the hanna calibration sequence. All I really need is the route to the function or the function itself that calibrates the probe to the board. In the library, its a serial thing, but i need to make it fool proof. I need to be able to calibrate the probe at pH 4.00 and pH 7.00 simply by selecting the calibration function using 1 or 2 buttons. Iv been arduino'ing for a long time and I just need someone to help me out with the library. This would be fine for a technical person, but unfortunately the people the ph controllers are going to are not computer people. Currently you have to send the firmware serial commands via the pc to start the process and to finish it. My problem is the calibration of the electrode. GitHub - DFRobot/DFRobot_PH: Arduino library for Gravity: Analog pH Sensor / Meter Kit V2, SKU: SEN0161-V2 The pH has many applications in fields such as medicine, chemistry, and agriculture.I need some assistance with the ph meter v2 code, specifically the DFRobot_PH library. A pH of 7 indicates a neutral solution, while a pH below 7 indicates an acidic solution and a pH above 7 indicates an alkaline solution. The pH measures the acidity or alkalinity of a solution and is expressed as a number between 0 to 14. DFRobot offers a range of water quality sensor products with uniform size and interface that can meet the needs of various water quality testing and DIY multi-parameter water quality testers. Using this product along with a main control board and software library, you can easily build a plug-and-play pH meter without any welding. The ring PTFE membrane is not easily clogged, making the electrode suitable for long-term online detection. The Ag/AgCl gel electrolyte salt bridge reference system provides stable half-cell potential and excellent anti-pollution performance. The industry pH combination electrode features a sensitive glass membrane with low impedance, enabling it to perform fast and precise PH measurements with good thermal stability and reproducibility. The hardware-filtered output signal has low jitter, while the software library adopts a two-point calibration method that can automatically identify standard buffer solutions (4.0 and 7.0), making it simple and convenient to use. The voltage regulator chip on board has a wide voltage supply range of 3.3~5.5V, making it compatible with 5V and 3.3V main control boards such as Arduino and LattePanda. This device finds wide application in different fields like aquaponics, aquaculture, and environmental water testing. The DFRobot Gravity: Analog pH Meter Pro V2 is a specialized tool designed to measure the pH level of a solution and indicate its acidity or alkalinity.
