- Getting the voltage varies on what you're using. The PH for this sensor is not at 0v for a PH7 it's around 2.51v from the multi-meter and PH4 at 3.03. If you calculate the step, 2.51-3.03 =-0.52. The difference between ph4.01 and PH7 is 2.99.
- If you're using a Particle product like the Photon or Argon, be aware of a bug. It's a hardware issue with the analog ports fluctuating a ghost voltage. This fluctuation is enough at these low voltages reading to make your ph sway by .7 or more. To fix this, you'll need to add a 0.1uF cap between the analog port your using and ground.
- This PH electrode probe must be calibrated with standard buffer solution before each use, and the electrode probe cannot be tested continuously for a long time, which will shorten its life. There are two trimmers on the circuit board. One of them is for offset adjustment (closest to BNC connector) accomplished by removing the Ph probe and shorting the BNC connector with a wire. The other trimmer is an upper limit threshold for the digital output pin.
- Avoid cross- between solutions during measurement to avoid affecting measurement accuracy.
- The electrode should avoid long-term immersion in acidic fluoride solution.
- The electrode plug should be kept clean and dry.
- The external reference solution of the electrode is 3NKCL solution.
- The electrode is composed of a glass electrode and a silver chloride silver reference electrode, and is a measuring component of the meter for measuring the value of the aqueous solution.
- Open Source PH Meter: An analog PH meter specially designed for Arduino controller, with simple connection and program control, which is very convenient to measure the PH value of the solution.
- PH Composite Electrode: a plastic non-fillable composite electrode that uses a combination of a glass electrode and a reference electrode. It is a measuring element for a PH meter and is used to measure the hydrogen ion activity (PH) in an aqueous solution. The figure is a manual for convenient secondary development.
- Parameters: +5.00V; Measuring range: 0-14PH; Measuring temperature: 0-60°C; Accuracy: ±0.1pH (25°C); Response time: ≤1min.
- Interface Wiring: BNC/XH2.54 interface; with onboard power indicator. The pH sensor is connected to the onboard BNC interface, and the onboard XH2.54 interface is connected to the analog port of the controller.
- Note: It is the most accurate under the condition of 25℃/5V (the closer to this condition, the more accurate); the practical electrode needs to be checked (when measuring acidic/alkaline solutions, use PH-4/PH-9.18 buffer solution for calibration)
- This is an TDS (Total Dissolved Solids) Meter with gravity interface compatible with Arduino

FAQ:
Q: How do I install the pH sensor on my Arduino?
A: The pH sensor comes with 4 standoffs and screws. Use two of them for the Arduino. 1) Insert the base plate into the bottom portion of the housing. Keep in position with screws or hot glue. 2) Mount the pH sensor on the base plate. Secure to standoffs with screws.
Q: What is a pH regulator?
A: — The regulator is meant for reactions that start at a certain pH and naturally decrease/increase in pH due to the reaction. However, for many reactions, it is desired to stay at the starting pH. So, if the reaction deviates too far from the desired pH, this arduino project will pump in acid or base to bring the pH back to normal.
Q: What does the 0 mean in the pH value on Arduino?
A: The 0 represents a pH of 7.0. In order to be able to use it with Arduino this circuit adds an offset value to the value measured by the probe, so the ADC will only have to take samples of positive voltage values.
Q: How do you calculate the pH of a pH sensor?
A: The sensor is linear so by taking two points we can deduce the equation to convert the measured voltage to pH. The general formula would be y = mx + b, so we have to calculate m and b since x would be the voltage and y the pH. The result is y = -5.70x + 21.34.
