can this be running for monitoring 27/7 ?

is the tutorial for this PRO V2 is same with SEN0161 V2 as i could find anywhere the tutorial for PRO V2. Only can find this tutorial https://wiki.dfrobot.com/Gravity__Analog_pH_Sensor_Meter_Kit_V2_SKU_SEN0161-V2 . but i want to use PRO V2 for my company tank

Can this be used on microbit?
Is there any program that can be used on microbit?

Excuse me, admin, I want to ask how much current is on the sensor?

Would there be any harm to the sensor if I shortened the length of the cable on the V2 model? Also, what is the size of the threads that is on the end where the cable comes out of the probe?

Hi! Can I use this device to measure soil ph?

I am engaged in hydroponics, on the basis of your sensors collected automation system, but in three different systems there is a deviation of PH sensor SKU:SEN0169-V2 readings by 0.5. I want to understand what it can be connected with?

Hello, good morning, I want to buy a pH sensor and I am between these 4 options. I understand that one is more expensive than the other since they have added improvements, but based on what I review on their page I realize that all 4 have the same technical characteristics, I don't know if this is due to a lack of updating of their information.

a) SKU:SEN0161 (https://www.dfrobot.com/pro...
b) SKU:SEN0161-V2 (https://www.dfrobot.com/pro...
c) SKU:SEN0169 (https://www.dfrobot.com/pro...
d) SKU:SEN0169-V2 (https://www.dfrobot.com/pro...

I would appreciate it if you could provide me with the following information:

1. Updated technical data of each of the sensors.
2. Which of the 4 sensors includes the buffer solutions (PH=4 and PH=7) for calibration.

And finally, if I buy two or three materials in the same order, the shipping cost is paid only once or for each item purchased and how much the shipping cost would be to my country, Peru.

Finally, how long would it take for my order to arrive in Peru, the city of Lima.

I await your prompt response.

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 without the power supply for a long time.

Could you please kindly explain why this is? Thank you.

Buenos días, Me puedes enviar un correo para solicitar la compra mediante empresa (Gravedad: sensor de pH industrial analógico / kit de medidor Pro V2)

Hello, im having trouble when meeassuring with 10cm of water above the sensor (under arround 2L of water) the sensor is screwed to a recrangular container from one of its sides. With little water level over the sensor it meassures just fine but at certain level of water the sensor stops reading and outputs a constant value. Any idea why?

Can you provide us the technical drawing for the board and probe ?

For my newly received sensor, there is a problem with calibration. When put in the 7.0 buffer, the voltage is 1720. That is just out of the range of the code for calibration in the DFRobot_PH library. this code only recogizes the 7.0 calibration if (voltage>1322 and voltage<1678):. See https://github.com/DFRobot/DFRobot_PH/blob/master/python/raspberrypi/DFRobot_PH.py
At 4.0, calibration is working fine.
Does this high voltage reading means there is something wrong with my sensor? How can I do the calibration now?
Thank you!

Yes, ADS1115 need to be connectted with raspberry pi SCL/SDA pins.
For more information about ADS1115, see the link below.

Thats depend. If you use it quite often, you have to calibrate it once a week.
For normal use, once a month is ok.

Yes, you can modify the code. For example, use several digital input, each one for one kinds of calibration (enter, 4 ,7)
Just use the API we provide in the library and you can easily do it.

Hi! Is this compatible with the Raspberry Pi 4B 8GB RAM, or with any ESP32?

Hi. I have the setup working and am able to see PH reading output. But on the same arduino Im also using a level sensor and a temperature sensor which I publish via mqtt. I'm still in trial and error. So I have to upload new code to my arduino every now and then. But after each upload the PH output is back to "nan" and then I need to execute the calibration each time before a meaningful PH value comes. That s really unpractical because my PH sensor is already installed and I decouple the arduino to make code changes. Also costly in terms of calibration fluid.
Is this normal behavior, or is there something I can do so that the calibration is stored even after uploads?
Thx

from where i can get the ph prob liquid and i purchased sensor from your store but i need the liquid

Yes, those two module using the same library.

What should I do? To test the probe I connect it to 5V and output to a voltmeter - it gives me a reading of ~1.9V which starts dropping and within a minute or two it reaches zero (and sometimes below). It doesn't react to the probe being in pH7 or pH4 solution - the voltage output is still the same.
