GAOHOU PH0-14 Value Detect Sensor Module + PH Electrode Probe BNC For Arduino

Response time:≤5S;Settling Time:≤60S;Component Power:≤0.5W;Detectable concentration range: PH0-14;Module Size: 42mm×32mm×20mm;Output: analog voltage signal output;With 4pcs M3 Mounting Holes
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.

FAQ:

Q: Which is the best soil sensor for Arduino?

A: The JXCT Soil NPK sensor is a low cost, quick responsive, high precision & portable Sensor that works with Modbus RS485. The advantage of this sensor over a traditional detection method is that it gives very fast measurement & data are highly accurate. All you need is to insert its probe in soil and get the reading using Arduino.

Q: What is the accuracy of the Arduino soil NPK sensor?

A: While talking about the accuracy of the sensor, it is up to within 2%. The nitrogen, phosphorous & potassium measuring resolution is up to 1mg/kg (mg/l). Using this Soil NPK Sensor, you can make your own Arduino Soil NPK Meter or any Cloud IoT Based Soil Nutrient Content Monitoring System.

Q: Is there a gas sensor for ammonia in water?

A: Googleing hasn’t found me anything but the MQ-137 which is a gas sensor for ammonia, not liquid. Think you fish will not like these test methods, but some google gave this lead – http://www.sensortips.com/zlevel/sensor-measures-dissolved-nitrate-in-water/ –

Q: What is the learn mode of an Arduino spectrometer?

A: The spectrometer has a “learn” mode and an “identify” mode. In the learn mode a known sample is placed in the unit and sampled at each wavelength of light emitted by the LED’s. The sampled values are stored in a database in the Arduino memory.
